Question

Please help with 4-9!!!

Answer 1

4. m = 10

5. q = 133

6. z = -143

7. c = 25

8. t = 52

9. p = 8

Explanation:

4)
`(3m+15)/(2) = 22.5`

`3m = 2(22.5)-15`

`m=(30)/(3)`

`m=10`

5)
`21=(q+35)/(8)`

`168-35= q`

`q=133`

6)
`14+(4z)/(-11) =66`

`(4z)/(-11) = 66-14`

`4z= 52 * -11`

`z= (-572)/(4)`

`z= -143`

7)
`(3)/(5c) -6=9`

`(3)/(5c) =9+6`

`3c=15*5`

`c=(75)/(3)`

`c=25`

8)
`(t)/(-2) +17 = -9`

`(t)/(-2) = -9-17`

`t= -26 * -2`

`t=52`

9)
`-6=(5p-(-2))/(-7)`

`42=5p+2`

`5p=42-2`

`p=(40)/(5)`

`p= 8`

Answer 2

sdfsdf

4)
`(3m+15)/(2) = 22.5`

Multiply by 2 on both sides

3m + 15 = 45

Subtract both sides by 15

3m = 30

Divide both sides by 3

so m = 3

5)
`21= (q+35)/(8)`

Multiply both sides by 8

168 = q + 35

Subtract both sides by 35

q = 133

6)
`14 + (4z)/(-11) = 66`

Subtract 14 from both sides

`(4z)/(-11) = 52`

multiply by -11 on both sides

4x = 572

Divide both sides by 4

x= 143

7)
`(3)/(5) c - 6 = 9`

Add 6 on both sides

`(3)/(5) c  = 15`

Multiply both sides by 5

3c = 75

Divide both sides by 3

c = 25

8)
`(t)/(-2) + 17 = -9`

Subtract both sides by 17

`(t)/(-2) =26`

Multiply both sides by -2

t = -52

9)
`-6 = (5p-(-2))/(-7)`

Multiply both sides by -7

42= 5p + 2

subtract 2 from both sides

40 = 5p

Divide both sides by 5

so p = 8
