The number of boys in the classroom is three more than the number of girls if there are 19 students how many are boys and how many are girls

Respuesta :

Answer:

11 boys 8 girls

Step-by-step explanation:

There are 19 total students.

There are 3 more boys than girls

girls + 3 = boys ( because there are three more boys)

boys + girls = 19

You can substitute g +3 for b so:

2 girls +3 = 19

19 - 3 = 16

16/2 = girls

8 = girls

Once you find g just subtract the amount of girls from 19 to get the amount of boys.

19 kids - 8 girls = 11 boys
