Question

Find the value of x

I would like all 3 answers and how to get them (show work).

Thanks!

Answer 1

4) 4

5) 6.5

6) 14

Explanation:

Question 4 equation:
`((12*5)/(2) * 2) + ((5x)/(2) *2) = 80` ⇒
`60 + 5x = 80` ⇒
`5x = 20` ⇒
`x=4`.

Question 5 equation:
`16x=104` ⇒
`x=6.5`.

Question 6 equation:
`(10x)/(2) = 70` ⇒
`5x=70` ⇒
`x=14`.
