2x +3=5 so what is the value of x
Answers
Answer:
x = 1
Step-by-step explanation:
2x + 3 = 5
=> 2x = 5-3
=> 2x = 2
=> x = 2/2
=> x = 1
Therefore, the value of x is 1
Hope it helps :)
Answer:
x=1
Step-by-step explanation:
Hi there!
2x+3=5
Our goal is to isolate x on one side of the equal sign, and we can do this using inverse operations. For example, the inverse operation of addition is subtraction. Subtract both sides of the equation by 3 to isolate 2x:
2x+3-3=5-3
2x=2
The inverse of multiplication is division. Divide both sides by 2:
2x÷2=2÷2
x=1

Now you will write an informative paragraph that will help Frankie to understand his financial options and formulate best practices for spending and saving.
Answers
Answer:
Strategies that Frankie should consider:
1.) What he needs vs what he wants (does Frankie need new shoes?)
2.) Opportunity cost (savings Frankie would have to give up if he buys new shoes)
3.) Short-term and long-term goals (Does Frankie needs shoes now, or can he wait?)
Frankie should think about a number of options before purchasing a new pair of shoes. He should first consider whether he actually needs or wants these shoes. He should then think about opportunity cost. How else could he have used that money if he had not purchased the shoes? Could he have utilized his resources more effectively? He must also think about the issue of setting goals. He needs to decide if this is a task for the present or the future.

What is a right-angled triangle?'A triangle in which one of the interior angles is 90° is called a right-angled triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the perpendicular and the base.'
According to the given ,
Perpendicular = 3
Hypotenuse = x
We know,
sin∅ = 3/x
∅ = 30°
⇒ sin30 = 3/x
⇒ 1/2 = 3/x [ sin30 = /2 ]
⇒ x = 3 * 2
⇒ x= 6
Hypotenuse = 6
Applying Pythagoras theorem:
Hypotenuse² = Perpendicular² + Base²
6² = 3² + Base²
6² - 3² = Base²
Base² = 25
Base = √25
Base = 5
We can conclude the value of x to be 6.

Given L || M find the value of unknown angles in each of the following figures
Answers
Answer:
Angle x = 120 degrees
Angle y = 60 degrees
Step-by-step explanation: Angle x has to be equivalent to the 120 degree angle that is already given since lines l and m are parallel as well as lines p and q. To find angle y, you must realize that angles x and y are supplementary angles, so their sum is 180 degrees. Since we now know that angle x is 120 degrees, you must subtract 120 from 180 in order to find the value of angle y: 180 - 120 = 60 degrees. I'm sure that there are other methods to figuring this question out, but this is how I did it.

the equation in the form of slope interpretation is y = 1/3x -4.
What is a Linear equation?An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation has the conventional form y = mx + c.
Given data in a table such as it makes a linear equation slope-intercept form of the given equation is y = mx +c
Where m is the slope
c is constant
The slope for the given data
m = (y₂ - y₁) / (x₂ - x₁)
m = (-5 + 6 )/ (-3 + 6)
m = 1/3
Hence, the equation would be
y = 1/3x + c
for constant we would satisfy the equation with other coordinates of the line.
Substituting ( 0, -4) in the above equation
-4 = 0 + c
c = -4
thus, the equation of the line is y = 1/3x -4
therefore, the linear equation of the given data is y = 1/3x -4.

Nico is trying to divide a 6 by 4 inches of rectangular cartoon sheet into pieces of squares. Given that he used up all of the materials and that all squares are of similar dimensions, what is the minimum number of squares he can produce?
Answers
Answer:
Minimum of 6 squares.
Step-by-step explanation:
The dimension of the rectangular carton = 6 by 4 inches.
The area of the carton = length x width
= 6 x 4
= 24 square inches
Assume that we have a square of side length 2 inches, then;
area of the square = length x length
= 2 x 2
= 4 square inches
So that since all materials is to be used,
the minimum number of squares that it can produce = [tex]\frac{24}{4}[/tex]
= 6
The minimum number of squares he can produce is 6.

How to analyze a hiperbolaIn this question we must analyze the general equation of a hyperbola and derive all the required information by algebraic and graphic means. All this information is derived from the standard equation of the hyperbola, which is presented below:
[tex]\frac{(x-h)^{2}}{a^{2}}-\frac{(y-k)^{2}}{b^{2}} = 1[/tex] (1)
Where:
a - Horizontal axis distanceb - Vertical axis distance h, k - Coordinates of the center of the hyperbola.The foci are located at the following two points: [tex]F_{1} (x, y) = (h - c, k)[/tex], [tex]F_{2} (x,y) = (h + c, k)[/tex].
Where [tex]c = \sqrt{a^{2}+b^{2}}[/tex].
And the asymptotes of the hyperbola are described by the following formulas:
y₁ = b · (x - h) / a + k (2)
y₂ = - b · (x - h) / a + k (3)
a) We transform the general equation into its standard form:
4 · x² + 8 · x - 9 · y² - 36 · y - 68 = 0 Given(2 · x)² + 4 · (2 · x) - (3 · y)² - 12 · (3 · y) - 68 = 0 Definition of power/Associative and commutative properties/Definition of multiplication[(2 · x)²+ 2 · 2 · (2 · x) + 4] - [(3 · y)² + 2 · 6 · (3 · y) + 36] + 36 - 68 - 4 = 0 Compatiblity with addition/Definition of multiplication/Commutative and associative properties/(-1) · a = - a(2 · x + 2)² - (3 · y + 6)² - 36 = 0 Perfect square trinomial/Definition of addition4 · (x + 1)² - 9 · (y + 2)² = 36 Compatibility with addition/Existence of additive inverse/Modulative property[tex]\frac{(x+1)^{2}}{3^{2}}-\frac{(y+2)^{2}}{2^{2}} = 1[/tex] Definition of power/Compatibility with multiplication/Existence of multiplicative inverse/ResultThe standard equation of the hiperbola is [tex]\frac{(x+1)^{2}}{3^{2}}-\frac{(y+2)^{2}}{2^{2}} = 1[/tex].

b) From the result found in a) we conclude that the center of the hyperbola is (h, k) = (-1, -2).
c) The foci of the hyperbola are located at the following two points:
[tex]c = \sqrt{3^{2}+2^{2}}[/tex]
[tex]c = \sqrt{13}[/tex]
F₁ (x, y) = (-1 - √13, -2), F₂ (x, y) = (-1 + √13, -2)
The foci of the hyperbola are F₁ (x, y) = (-1 - √13, -2) and F₂ (x, y) = (-1 + √13, -2). [tex]\blacksquare[/tex]
d) And the asymptotes of the hyperbola are presented below:
y₁ = 2 · x / 3 (2)

Answer:
The equation of the hyperbola = (x + 1)^2/3^2 - (y + 2)^2/2^2 = 1
The center of the hyperbola = (-1, -2) (h, k)
The vertices of the hyperbola (my assingment asked me for vertices) = (2, -2) and (-4, 2)
The asymptotes = one at y = (2x+2/3) - 2 and the other is at
y = -((2x+2/3) -2)).
Step-by-step explanation:
For the graphing part plug the equation into desm0s and the asymptote equation. For the guiding box part, you use the B variable. Since b = 2 in this problem, you count up two spaces from the center (-1,-2) and then down two spaces. These will be the top and bottom of your guiding box. Then use your vertices as the sides and make a box that connects.

Answers
Answer:
perimeter = 70 yards
Step-by-step explanation:
⭐What is the area of a rectangle?
area = length * width⭐What is the perimeter of a rectangle?
perimeter = 2(length) + 2(width)Strategy1. Make the equation for the area of the given rectangle and solve for x
2. Substitute x into the expressions of the length and width and solve for the perimeter
Working1. Define the expressions of the length and width of the rectangle
width: x
length: 4x
2. Make the equation for the area of the rectangle
[tex]196yd^2 = 4x * x\\196yd^2 = 4x^2[/tex]
3. Solve for x
[tex]\frac{196}{4} = x^2[/tex] . . . . . . . . . . divide both sides by 4
[tex]49 = x^2[/tex]
[tex]\sqrt{49} = \sqrt{x^2}[/tex] . . . . . . . . square root both sides to isolate x
∴ [tex]7 = x[/tex]
4. Substitute x into the expressions of the length and the width
width: x
width = 7
height: 4x
height = 4(7) = 28
5. Solve for the perimeter
[tex]perimeter = 2(length) + 2(width)[/tex]
[tex]perimeter = 2(28) + 2(7)\\perimeter = 56 + 14\\perimeter = 70[/tex]
