Why are unknown values represented using variables when solving problems?We may build equations that link unknown values in a problem and describe those numbers using variables. We may modify these equations algebraically to get solutions for the unknowable numbers by employing variables. As a result, issue solving is more effective and we can come up with generic answers that may be used in a variety of situations. Moreover, employing variables enables us to see patterns and trends as well as better grasp the connections between various amounts in a situation.
Given that,
Ryan sent 7 fewer messages than Martina.
R = M - 7
Keith sent 2 times as many messages as Martina.
K = 2M
Martina, Ryan, and Keith sent a total of 77 text messages.
M + R + K = 77
Substitute the value of equation 1 and 2 in equation 3:
M + (M - 7) + 2M = 77
4M - 7 = 77
4M = 84
M = 21
Substitute the value of M in equation 1 and equation2:
R = M - 7 = 21 - 7 = 14
K = 2M = 2(21) = 42
Hence, the number of messages are: Martina sent 21 messages, Ryan sent 14 messages, and Keith sent 42 messages.

Hello! 5/6 2/5 in simplest form
Answer:
Step-by-step explanation:
5/6 - 2/5 = 25/30 - 12/30 = 13/30
Answer:
Step-by-step explanation:
To subtract two fractions, we need a common denominator. The smallest number that 6 and 5 both divide into is 30.
Converting the fractions to have 30 as the denominator, we get:
5/6 = 25/30
2/5 = 12/30
Now we can subtract:
25/30 - 12/30 = 13/30
Therefore, 5/6 - 2/5 = 13/30 in simplest form.

How to determine an equation of this line?In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.At data point (1000, 19), a linear function in standard form for this line can be calculated by using the point-slope form as follows:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 19 = (16 - 19)/(2000 - 1000)(x - 1,000)
y - 19 = -0.003(x - 1,000)
y = -0.003x + 3 + 19

Describe function ?The input values of a function are called the domain, and the output values are called the range. The domain can be any set of values, but each input value must have a unique corresponding output value. If there are multiple input values that produce the same output value, the function is not considered to be well-defined. Functions are used to model a wide range of phenomena in many different fields, including science, engineering, and economics. They are also used in calculus to study rates of change and slopes of curves.
To find f(x+h), we need to replace x with (x+h) in the given function:
f(x+h) = -4(x+h)² - 4(x+h) - 1
= -4(x² + 2xh + h²) - 4x - 4h - 1
= -4x² - 8xh - 4h² - 4x - 4h - 1
To find (f(x+h) - f(x))/h, we first need to find f(x):
f(x) = -4x² - 4x - 1
Then we can substitute f(x+h) and f(x) in the formula:
(f(x+h) - f(x))/h = (-4x² - 8xh - 4h² - 4x - 4h - 1 - (-4x² - 4x - 1))/h
= (-4x² - 8xh - 4h² - 4x - 4h - 1 + 4x^2 + 4x + 1)/h
= (-8xh - 4h² - 4h)/h
= -8x - 4h - 4
So, f(x+h) = -4x² - 8xh - 4h² - 4x - 4h - 1, and (f(x+h) - f(x))/h = -8x - 4h - 4.

As a result, the total quilt's area is 512/9 square inches.
What is square used for?Square offers businesses a range of goods and services to help them complete sales deals, use marketing strategies, and control their finances, inventory, and workforce.
The quilt has an 8 x 8 array of square patches, which means it has a total of 8 x 8 = 64 square patches. Each square patch is 2 2/3 inches long.
To find the area of the whole quilt, we need to find the total area covered by all 64 square patches. We can do this by multiplying the length and width of one square patch by the total number of patches:
Area of one square patch = length x width = (2 2/3 in) x (2 2/3 in) = (8/3 in) x (8/3 in) = 64/9 sq in
Total area of all 64 square patches = (64 patches) x (64/9 sq in per patch) = 512/9 sq in
Therefore, the area of the whole quilt is 512/9 square inches.

The volume of a cone whose height h and base radius is r is given by the formula of the volume of a cone,express r in terms of v,pie and h and find the value of h when the volume of the cone is 660cm raise to power 3,where r is 14cm(pie=22/7)
The formula for the volume of a cone is:
V = (1/3)πr^2h
Solving for r:
V = (1/3)πr^2h
3V = πr^2h
r^2 = (3V)/(πh)
r = sqrt[(3V)/(πh)]
Given that V = 660cm^3, h = 14cm and π = 22/7:
r = sqrt[(3 × 660)/(22/7 × 14)] ≈ 7 cm
So the radius is approximately 7 cm.
To find the value of h:
V = (1/3)πr^2h
660 = (1/3)(22/7)(7^2)h
660 = (22/3)(49/7)h
660 = (22/3)(7)h
h = 660 / [(22/3)(7)]
h = 9.45 cm (rounded to two decimal places)
Therefore, the value of h when the volume of the cone is 660 cm^3 is approximately 9.45 cm.

the parallelogram below has an area of 54 units²
The height of the parallelogram is 5.4 units.
What is area ?
In mathematics, the area is the measure of the size of a two-dimensional surface or region, usually expressed in square units, such as square inches or square meters. The area of a flat shape or planar figure is the amount of space inside its boundary, or the surface of the object, that is covered by a two-dimensional geometric shape.
One way to find the height is to draw a perpendicular line from point B to line segment AD, forming a right triangle. Let's call the length of this perpendicular line h.
Now we can see that the base of the parallelogram is 10 units (from A to D), and the height is h units (from B to the perpendicular line we drew). The area of the parallelogram is given as 54 units², so we can set up the following equation:
Area = base x height
54 = 10h
Solving for h, we get:
h = 54/10 = 5.4
Therefore, the height of the parallelogram is 5.4 units.

What are the solutions to the quadratic equation x2 - 10x + 18 = 0
Answer:
x = 5 + [tex]\sqrt{7}[/tex]
x = 5 - [tex]\sqrt{7}[/tex]
Step-by-step explanation:
The given quadratic equation is:
x^2 - 10x + 18 = 0
We can solve this equation using the quadratic formula, which states that for a quadratic equation of the form ax^2 + bx + c = 0, the solutions for x are given by:
x = (-b ± sqrt(b^2 - 4ac)) / 2a
In this case, a = 1, b = -10, and c = 18. Substituting these values into the quadratic formula, we get:
x = (-(-10) ± sqrt((-10)^2 - 4(1)(18))) / 2(1)
Simplifying the expression inside the square root, we get:
x = (10 ± sqrt(100 - 72)) / 2
x = (10 ± sqrt(28)) / 2
x = (10 ± 2sqrt(7)) / 2
