Answer:
-2
Step-by-step explanation:
5(2z + 4) = 0
Divide both sides by 5.
2z + 4 = 0
Subtract 4 from both sides.
2z = -4
Divide both sides by 2.
z = -2
Answer:
<h3>X=-1/8=-0.125</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
x+2/4=3/8
2/4=1/2 (First, use the common factor of 2.)
x+1/2=3/8
x+1/2-1/2=3/8-1/2 (Then, subtract 1/2 from both sides.)
3/8-1/2 (Solve.)
3/8-1/2=-1/8
-1/8=-0.125
x=-1/8=-0.125
In conclusion, the final answer is x=-1/8=-0.125.
I would set this up as a a proportion:
