Answer:

r = 7

Step-by-step explanation:

Given

r + 15 = 4r - 6 ( subtract 4r from both sides )

- 3r + 15 = - 6 ( subtract 15 from both sides )

- 3r = - 21 ( divide both sides by - 3 )

r = 7

The value of y varies directly with x. If x = 8, then y = 96. What is the value of x when y = 168?

patriot [66]

Answer:

x = 14

Step-by-step explanation:

Direct variation equation:

y = kx, where k is constant of variation

Given:

96 = 8k
k = 96/8
k = 12

The equation is:

y = 12x

Find the value of x when y = 168:

168 = 12x
x = 168/12
x = 14
