Question

Can anyone help me if i dont get my grade up i wont get to go to my vollyball games

Answer 1

`(3)/(8) x + (1)/(3) x = 28`

`(9)/(24) x + (8)/(24)x = 28`

`(17)/(24) x = 28`

`x = 28 / (17)/(24)`

`x = 28 * (24)/(17)`

`x = (672)/(17)`

Answer : 672/17

The picture is the proof

Answer 2

x = 30

Explanation:

`(3)/(5)`(30) +
`(1)/(3)`(30) = 28

`(3)/(5)`(30) = 18

`(1)/(3)`(30) = 10

18 + 10 = 28
