Question

Please help me with this homework

Answer 1

7.
`a=48`

8.
`b=30`

9.
`c = 188`

10.
`d = 18`

11.
`x = 32`

12.
`y = 40`

Explanation:

Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.

`(33)/(a) = (11)/(16)`

`11 a = 33(16)`

`11a = 528`

Now we can simplify.

`a=48`

So we got the answer for the first one. We can keep doing the same thing for the others.
