Question

8th grade math!!! PLEASE HELP BRAINLIST

Answer 1

There are 55 girls in the eighth grade

Representation

Represent the boys with b, and the girls with g.

System of equations

So, the equations are:

$b = 100 - g$

$g=10 + b$

Substitute 10 + b for g in the first equation

$b=100 - (10 +b)$

Expand the equation

$b=100 - 10 -b$

Add b to both sides of the equation

$2b=100 - 10$

$2b=90$

Divide both sides by 2

$b=45$

Substitute 45 for b in $g=10 + b$

$g =10 + 45$

$g =55$

Hence, there are 55 girls in the eighth grade
