Question

Please help with 4-9!!!

Answer 1

Answer:

4. m = 10

5. q = 133

6. z = -143

7. c = 25

8. t = 52

9. p = 8

Step-by-step explanation:

4) $\frac{3m+15}{2} = 22.5$

$3m = 2(22.5)-15$

$m=\frac{30}{3}$

$m=10$

5) $21=\frac{q+35}{8}$

$168-35= q$

$q=133$

6) $14+\frac{4z}{-11} =66$

$\frac{4z}{-11} = 66-14$

$4z= 52 * -11$

$z= \frac{-572}{4}$

$z= -143$

7) $\frac{3}{5c} -6=9$

$\frac{3}{5c} =9+6$

$3c=15*5$

$c=\frac{75}{3}$

$c=25$

8) $\frac{t}{-2} +17 = -9$

$\frac{t}{-2} = -9-17$

$t= -26 * -2$

$t=52$

9) $-6=\frac{5p-(-2)}{-7}$

$42=5p+2$

$5p=42-2$

$p=\frac{40}{5}$

$p= 8$

Answer 2

sdfsdf

4) $\frac{3m+15}{2} = 22.5$

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) $21= \frac{q+35}{8}$

Multiply both sides by 8

168 = q + 35

Subtract both sides by 35

q = 133

6) $14 + \frac{4z}{-11} = 66$

Subtract 14 from both sides

$\frac{4z}{-11} = 52$

multiply by -11 on both sides

4x = 572

Divide both sides by 4

x= 143

7) $\frac{3}{5} c - 6 = 9$

Add 6 on both sides

$\frac{3}{5} c = 15$

Multiply both sides by 5

3c = 75

Divide both sides by 3

c = 25

8) $\frac{t}{-2} + 17 = -9$

Subtract both sides by 17

$\frac{t}{-2} =26$

Multiply both sides by -2

t = -52

9) $-6 = \frac{5p-(-2)}{-7}$

Multiply both sides by -7

42= 5p + 2

subtract 2 from both sides

40 = 5p

Divide both sides by 5

so p = 8
