There are 189 students in the band the difference between the number of boys and the number of girls is 27 how many boys and girls each are in the band

108 boys and 81 girls

Step-by-step explanation:

If B is the number of boys and G is the number of girls, then:

B + G = 189

B - G = 27

To solve, use substitution or elimination. In this case, I recommend elimination. Add the equations together:

2B = 216

B = 108

Therefore:

G = 81

So there are 108 boys and 81 girls.
