The variables y and x have a proportional relationship, and y = 12 when x = 5. What is the value of y when x = 8?

y=19.2

Step-by-step explanation:

Here as y is proportional to x

so

y=kx

When y = 12 , x = 5

We have

12 = 5k

k = 12/5=2.4

So now we have

y=2.4x

When x = 8

y = 2.4(8)

y = 19.2
