Answer:

Step-by-step explanation:

Look for the GCF and then divide every term by the GCF to see what remains

(9) 5a - 25 ( GCF is 5 so take out 5 and divide every term by 5)

5(a-5)

(10) 28 - 7x ( GCF is 7 so take out 7 and divide every term by 7)

7(4-x)

(11) 12z + 28 - 7z - 3= (combine terms) =

5x+25( GCF is 5 so take out 5 and divide every term by 5)

5(x+5)

3/4(x+5 1/2) = 5/8 Distributive Property Brainly

Talja [164]

Answer:

x = - $\frac{14}{3}$

Step-by-step explanation:

Given

$\frac{3}{4}$ (x + 5 $\frac{1}{2}$ ) = $\frac{5}{8}$

Multiply both sides by 8 to clear the fractions

6(x + 5 $\frac{1}{2}$ ) = 5 ← distribute parenthesis on left side

6x + 33 = 5 ( subtract 33 from both sides )

6x = - 28 ( divide both sides by 6 )

x = $\frac{-28}{6}$ = - $\frac{14}{3}$
