Suppose y varies directly as x and y = 20 when x = 8. What is the value ofy whenx = 12?
y =__
Answers
Answer:
y = 30
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in 20 as y and 8 as x, then solve for k:
y = kx
20 = k(8)
2.5 = k
So, the equation is y = 2.5x
Plug in 12 as x, and solve for y:
y = 2.5x
y = 2.5(12)
y = 30
So, when x = 12, y = 30

Answer:
5
2y
40
Step-by-step explanation:
Answer:
y = 5
Because [2y] is on both sides of the equation, 8y must be equal to [40] so that the equation is true.
Step-by-step explanation:
Combine like terms to find the value of y.
8y + 2y = 2y + 40
10y = 2y + 40
8y = 40
y = 5
As we can see, we ended with 8y = 40, and 2y is the only term on both sides of the equation.

In triangle ABC, m∠A=(2x+2)∘, m∠C=54∘, and the exterior angle at B is (4x)∘.
Triangle A B C. Angle A is 2 X plus 2 degrees, angle C is 54 degrees, & the exterior angle at B is 4 X degrees.
What is the measure of angle A?
58∘
112∘
28∘
68∘
Answers
Answer:
58°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the two remote interior angles.
m∠A + m∠C = measure of exterior angle at B
2x + 2 + 54 = 4x
2x + 56 = 4x
2x = 56
x = 28
m∠A = 2x + 2 = 2(28) + 2 = 56 + 2 = 58°
Answer:
A
Step-by-step explanation:
Remark
<A + <C = the exterior angle.
Two remote interior angles = the exterior angle that neither connects to.
Remote means that the angles do not share any line in common with the remote angle. One of them might share a line extended with the exterior angle.
Equation
<A + <C = Remote angle connected to the supplement of B
Givens
m<A = 2x + 2
m<C = 54
Remote angle = 4x
Solution
2x + 2 + 54 = 4x Combine like terms on the left
2x + 56 = 4x Subtract 2x from both sides
56 = 4x - 2x
2x = 56 Divide by 2
x = 56/2
x = 28
Answer
<A = 2x + 2
<A = 2*28 + 2
<A = 56 + 2
<A = 58
Given h(x) = -X – 2, solve for x when h(x) = 3.
Answers
Answer:
x = -5
Step-by-step explanation:
One is given a function and the value of the function at a certain output. One must set the function to the given output, and solve to find the input,
h(x) = - x - 2
h(x) = 3
Set the output equal to the input,
h(x) = - x - 2 = 3
Inverse operations,
- x - 2 = 3

r=14 in
Step-by-step explanation:
The volume of a cylinder is given by:
[tex]v = \pi \times {r}^{2} \times h[/tex]
So,
[tex]r = \sqrt{ \frac{v}{\pi \times h} } = \sqrt{ \frac{196 \times \pi}{\pi \times 1} } = \sqrt{196} = 14[/tex]
Step-by-step explanation:
solution given.:
radius[r] =r
height[h]=1in
volume[V] of cylinder=196πin³
we have
volume[V] of cylinder=πr²h
196π=πr×1
r²=[tex] \frac{196π}{π}[/tex]
r=[tex] \sqrt{196} [/tex]
r=14in

16. Which of the following
numbers should go in the
space to make the equation
true?
(4 x 2) × (6-3) = 4 x_x2
Answers
Answer: 3
Step-by-step explanation: Start off by solving the right side of the equation: 4 x 2 is 8 and 6 - 3 is 3, and then you must do 8 x 3 which is 24. Now, the equation should look like this: 24 = 4 x _ x 2. Next, you should go a step further with the left side of the equation by multiplying 4 and 2. Now, the equation should look like this: 24 = 8 x _. For the final step, you must divide 8 on both sides to solve for the missing number. Since 24 divided by 8 is 3, your answer is 3.
