Answer:
x=13
Step-by-step explanation:
I guess the angles are supplementary,Which means they have a sum of 180°.
11x - 15+5x-13=180
16x-28=180
16x=208
x=13
(b)+(b+45)=215
b = # of boys
there are 45 more girls than boys and 215 students total.
minus 45 on both sides leaving you with
(b)+(b)=170
combine like terms leaving you with
2b=170
divide both sides by 2
b=85
there were 85 boys
85+45=130
(the 45 for the # of girls more than boys)
there were 130 girls.
