Answer 1

Answer:

number of boys is 44

Step-by-step explanation:

number of girls is=x

number of boys is=2x-10

therefor

(2x-10)+(x)=71

2x-10+x=71

3x=71+10

3x=81

x=81/3

x=27

number of boys=2x-10

                          =2(27)-10

                           =54-10

                              =44
