Answer:Annabelle is right
Step-by-step explanation:
match the answers only annebelles answer matches the actual answer
Factor out like terms
-y(7+y)=0
Inverse operation is an operation that undoes what was done by the previous operation. Take this simple addition problem 5+2=7. If we want to reverse the addition, we just subtract 7-2=5 and we are back where we started. You do the same for multiplication and division.
Boys are b
Girls are g
b + g = 120
2g = b
Substitute the second equation into the first
2g + g = 120
3g = 120
g = 40
Plug in g = 40 and solve for b
b + g = 40
b + 40 = 120
b = 80
There are 40 girls and 80 boys.
