Let
x--------> amount of starting rocks George had
we know that
[tex]\frac{1}{2}(x+5)=36[/tex] ------> equation that could be used to determine how many rocks George started with
Solve for x
[tex]\frac{1}{2}(x+5)=36[/tex]
Multiply by [tex]2[/tex] both sides
[tex](x+5)=72[/tex]
Subtract [tex]5[/tex] both sides
[tex](x+5)-5=72-5[/tex]
[tex]x=67\ rocks[/tex]
therefore
the answer Part a) is
The equation that could be used to determine how many rocks George started with is [tex]\frac{1}{2}(x+5)=36[/tex]
the answer Part b) is
[tex]67\ rocks[/tex]
Answer:
1/2 (x+5) = 36 should be the equation that is used to determine how many rocks George started with
