Question

Help plsssssssssssssssssssssssssss

Answer 1

? = 5

Explanation:

You use cross-multiplying. Let's say ? is x.

First step:
`(30)/(x)=(48)/(8)`

Second step: You cross them so 30(8)= 280. 48(x)= 48x.

Third step:
`(280)/(48x)`= 5

To double check this:

30/5= 6

48/8= 6

42/7= 6

I hope this helps.

I did this while struggling with my homework too lol.
