Answer 5

Plugging in our initial statement values of x = 12 when x = 8, we get:
12 = 8k

Divide each side by 8 to solve for k:
12
8 = 8k
8

k = 1.5

Solve the second part of the variation equation:

Because we have found our relationship constant k = 1.5, we form our new variation equation:

x = 1.5x

Answer 6

Since we were given that x = 8, we have

x = 1.5(8)
