1/2 (5-2h) = h/2, solve for h

Answer:
h = 1 2/3
Step-by-step explanation:
1/2 (5-2h) = h/2
Multiply each side by 2
(5-2h) = h
Add 2h to each side
(5-2h +2h) = h+2h
5 = 3h
Divide by 3
5/3 = 3h/3
5/3 =h
1 2/3 = h
Check
1/2 (5-2*5/3) = 5/3/2
1/2 ( 5 - 10/3) = 5/6
1/2 ( 15/3 - 10/3) = 5/6
1/2 ( 5/3) = 5/6
5/6 = 5/6
Answer:
A
Step-by-step explanation:
So we have the equation:
[tex]\frac{1}{2}(5-2h)=\frac{h}{2}[/tex]
First, let's multiply both sides by 2 to get rid of the fractions. The 2s will cancel. So:
[tex]2(\frac{1}{2}(5-2h))=2(\frac{h}{2})[/tex]
Simplify:
[tex]5-2h=h[/tex]
Add 2h to both sides:
[tex]5=3h[/tex]
Divide both sides by 3:
[tex]h=5/3[/tex]
Change into mixed fractions:
[tex]h=1\frac{2}{3}[/tex]
So, our answer is A.
And we're done!
To check, substitute 5/3 back in:
[tex]\frac{1}{2}(5-2(5/3))=\frac{(5/3)}{2}[/tex]
Multiply and divide:
[tex]\frac{1}{2}(5-10/3)=\frac{5}{6}[/tex]
Subtract on the left:
[tex]\frac{1}{2}(5/3)=\frac{5}{6}[/tex]
Multiply:
[tex]\frac{5}{6}\stackrel{\checkmark}{=}\frac{5}{6}[/tex]
So, our answer is correct!
