Question

Y and x have a proportional relationship, and y=12 when x=8. What is the value of x when y=18?

Answer 1

x=12

its 12 because i took the quiz

Answer 2

x = 12

Explanation:

Proportional relationship means that
`(y)/(x)` = k(a constant)

Here, k = 12/8 = 3/2

So, the equation is
`(y)/(x)` = 3/2.

Plug in y = 18, and we get 18/x = 3/2.

18 = 3/2x

x = 12
