Answer 1

x=12
`(3)/(5)`

Explanation:

If two variables x and y are directly proportional, it means they have a relationship y=kx, where k is some constant.

We know when y=-0.6, x=0.24. Let's sub this into y=kx to find k:

-0.6=0.24k

-0.6/0.24 = (0.24/0.24)k

-2.5 = k

Now we know k=2.5, we know the relaitonship between x and y is y=-2.5x. So we can find the value of x when y=-31.5 by subbing this into y=-2.5x:

y=-2.5x

-31.5=-2.5x

-31.5/-2.5 = (-2.5/-2.5)x

12.6=x

As a mixed fraction, 12.6 is equal to 12
`(6)/(10)` or 12
`(3)/(5)`, so our answer is:

x=12
`(3)/(5)`

Answer 2

the answer is x= 12 3/5
