In linear equation, 3.99 does the amount of money left on the gift card change each month.
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.
Equations whose variables have a power of one are called linear equations. A single variable example with real values for a and b and x as the variable is ax+b = 0.

it is 4/10 of a milw to john's house from frank's house. How much less than a mile is the distance from frank's house to john's house and then back to frank's house
The distance from frank's house to john's house and then back to frank's house is less than a mile by 1/5 units.
How do you figure out the overall distance?Simply multiplying the distance between two points while travelling from one location to another and back will give you the total distance travelled when travelling from one location to another and returning to the starting point.
The distance from frank's house to john's house = 4/10.
The distance back to Frank's house = 4/10.
Total distance = 4/10 + 4/10
Total distance = 8/10
The distance is thus,
1 - 8/10
Take the LCM:
(10 - 8) / 10
2/10 = 1/5
Hence, the distance from frank's house to john's house and then back to frank's house is less than a mile by 1/5 units.

Where the above conditions exist:
the weight of each type of coffee in 800g of X is:650gthe weights of type P coffee and type R coffee in 800g of Y is: 480gthe ratio of the three types of coffee in Z is approximate: P : Q : R = 0.1125 : 0.5063 : 0.3the weight of P coffee in 800g of Z is: 90g.What is the rationale for the above response?(a) To find the weight of each type of coffee in 800g of X, we can use the ratio of P coffee to Q coffee in the blend, which is 3:13.
Let the weight of P coffee in 800g of X be 3x, then the weight of Q coffee in 800g of X is 13x.
The total weight of X is 800g, so we have:
3x + 13x = 800
16x = 800
x = 50
Therefore, the weight of P coffee in 800g of X is:
3x = 3(50) = 150g
And the weight of Q coffee in 800g of X is:
13x = 13(50) = 650g
(b) To find the weights of type P coffee and type R coffee in 800g of Y, we can use the ratio of the three types of coffee in the blend, which is 1:7:12 by weight.
Let the weight of P coffee in 800g of Y be x, then the weight of Q coffee in 800g of Y is 7x and the weight of R coffee in 800g of Y is 12x.
The total weight of Y is 800g, so we have:
x + 7x + 12x = 800
20x = 800
x = 40
Therefore, the weight of P coffee in 800g of Y is:
x = 40g
And the weight of R coffee in 800g of Y is:
12x = 12(40)
= 480g
(c) To find the ratio of the three types of coffee in a third standard blend Z, formed by mixing equal weights of X and Y, we first need to find the total weight of X and Y that will be used to make Z. Since we are mixing equal weights of X and Y, the total weight of X and Y in Z will be:
800g + 800g = 1600g
The ratio of P coffee to Q coffee in Z can be found by adding the weights of P coffee in X and Y, and then dividing by the total weight of X and Y:
(150g + 40g) / 1600g = 0.1125
Similarly, the ratio of Q coffee to the total weight in Z can be found by adding the weights of Q coffee in X and Y, and then dividing by the total weight of X and Y:
(650g + 7(40g)) / 1600g = 0.5063
The ratio of R coffee to the total weight in Z can be found by adding the weights of R coffee in Y, and then dividing by the total weight of X and Y:
(12(40g)) / 1600g = 0.3
Therefore, the ratio of the three types of coffee in Z is approximate:
P : Q : R = 0.1125 : 0.5063 : 0.3
(d) To find the weight of type P coffee in 800g of Z, we can use the ratio of P coffee to the total weight in Z, which is 0.1125.
Therefore, the weight of P coffee in 800g of Z is:
0.1125 * 800g = 90g

Consider the equation y^2+24= - 11y. What is the positive value of the square root of the product of the roots?
Therefore , the solution of the given problem of equation comes out to be the 2 * √6 is the positive value of the square root of the sum of the roots.
How do equations work?Mathematical formulas frequently use the same variable letter to try to impose uniformity between two claims. Many academic numbers are shown to be equal using mathematical expression, also known as assertions. The normalise divides 12 and b + 6 into two parts using the result y + 6 = 12 as an illustration. It is possible to determine the connection between each sign component and the number of lines. The significance of a symbol usually contradicts itself.
Here,
By modifying the equation y2 + 24 = -11y, we can first convert it to standard quadratic form:
=> y^2 + 11y + 24 = 0
Using the quadratic formula, we can now determine the quadratic's roots:
=> y = (-11 ± √11^2 - 4(1)(24)))/(2(1))
=> ( -11 ± √(121 - 96))/2
=> (-11 ± √(25))/2
Thus, y = -8 and y = -3 are the solutions.
What the roots produce is:
(-8) * (-3) = 24
Additionally, the product's square root's positive number is:
=> √(24) = 2 * √(6)
In light of this, 2 * √6 is the positive value of the square root of the sum of the roots.

A rectangle has 2 lines of symmetry.
What is a line of symmetry?
A line of symmetry is a line that divides a shape into two mirror-image halves. When a shape is divided by a line of symmetry, each half of the shape is a reflection of the other half, and they are said to be symmetric or mirror images of each other. In other words, if you were to fold the shape along its line of symmetry, the two halves would match up perfectly. The presence or absence of lines of symmetry is an important characteristic of shapes and can be used to identify and classify them.
Calculate the line of symmetry of a rectangle -
A rectangle has two lines of symmetry: one line that runs vertically down the center of the rectangle, and another line that runs horizontally across the center of the rectangle.
To understand why a rectangle has two lines of symmetry, consider that any line that runs down the center of a rectangle will divide it into two halves that are mirror images of each other. This is true for lines that run vertically or horizontally through the center of the rectangle.
In contrast, a rectangle does not have diagonal lines of symmetry. That is, there is no line that can be drawn from one corner of the rectangle to another corner that will divide it into two mirror-image halves.
Overall, a rectangle has two lines of symmetry, and these lines are important to its geometry and properties.

θ = π/4, 3π/4, 5π/4, 7π/4.
What is trigonometry?Trigonometry is the branch of mathematics which set up a relationship between the sides and angles of right-angle triangles.
Starting with the equation:
√2sinθ + 1 = 0
Subtracting 1 from both sides, we get:
√2sinθ = -1
Squaring both sides, we get:
2sin²θ = 1
Dividing both sides by 2, we get:
sin²θ = 1/2
Taking the square root of both sides, we get:
sinθ = ± √2/2
Using the unit circle, we know that sinθ = √2/2 at π/4 and 3π/4, and sinθ = -√2/2 at 5π/4 and 7π/4.
Therefore, we have:
sinθ = √2/2 at θ = π/4 + 2πn, 3π/4 + 2πn
sinθ = -√2/2 at θ = 5π/4 + 2πn, 7π/4 + 2πn

By answering the above question, we may state that As a result, the coordinates graph's line has the equation y = (4/5)x + 11/5.
what are coordinates?A coordinate system in geometry is a method that employs one or more integers or coordinates to identify the precise placement of points or other geometrical objects on a manifold, such as Euclidean space. Pairs of integers called coordinates are used to locate a point or object on a two-dimensional plane. The position of a point on a 2D plane is described by two integers known as the x and y coordinates. a group of numbers that represent precise positions. Usually, there are two numbers in the figure. The front-to-back distance is represented by the first number, while the top-to-bottom distance is represented by the second number. like in (12.5), when there are 12 units below and 5 above.
In order to determine the line's equation, we must first determine the slope (m) of the line using the following formula:
m = (y2 - y1) / (x2 - x1) (x2 - x1)
where the coordinates of the two sites the line travels through are (x1, y1) and (x2, y2), respectively.
In place of the values we hold:
m = (7 - 3) / (6 - 1) (6 - 1)
m = 4 / 5
Now that we have the slope, we can solve the equation of a line using the point-slope form, which is:
y - y1 = m(x - x1) (x - x1)
where one of the locations the line travels through is (x1, y1).
y - 3 = (4/5)(x - 1) (x - 1)
y = (4/5)x - 4/5 + 3 y = (4/5)x + 11/5 is equal to y - 3 = (4/5)x - 4/5.

Given that arc CA measures 78 degrees and arc DB measures 32 degrees, find the measurement of angle AXC.
Angle AXC is congruent to both angle CAX (78 degrees) and angle CDX (102 degrees), its measurement is also 102 degrees.
To find the measurement of angle AXC, we need to consider that it is an inscribed angle subtended by the same arc CX as arc CA and arc DB.
Inscribed angles that subtend the same arc are congruent. Therefore, we can conclude that angle AXC is congruent to both angle CAX and angle CDX.
Since angle CAX and angle CDX are supplementary angles (they add up to 180 degrees) and we know the measurement of angle CAX, we can find the measurement of angle CDX.
angle CAX + angle CDX = 180 degrees
78 degrees + angle CDX = 180 degrees
angle CDX = 180 degrees - 78 degrees
angle CDX = 102 degrees
Since angle AXC is congruent to both angle CAX (78 degrees) and angle CDX (102 degrees), its measurement is also 102 degrees.

What is the answer to 1/5x = 3/10?
Answer:
To solve for x, we can cross-multiply:
1/5x = 3/10
10(1/5x) = 10(3/10)
2x = 3
x = 3/2
Therefore, the solution is x = 3/2.
Answer:
To solve the equation 1/5x = 3/10 for x, we need to isolate x on one side of the equation.
First, we can simplify the equation by multiplying both sides by the reciprocal of 1/5, which is 5/1 or simply 5:
(1/5)x = 3/10
5(1/5)x = 5(3/10)
x = 3/2
Therefore, the solution to the equation 1/5x = 3/10 is x = 3/2 or 1.5.
