There are 12 more girls than boys in a drama club. the ratio of girls to boys is 9: 5. how many girls and how many boys are in the drama club

Step-by-step explanation:

boys:= x

girls:= x + 12

x/(x + 12) = 5/9             The 9 goes with the girls. There are more of them.

9x = 5(x+12)                  The step was cross multiply.

9x = 5x + 60                 Subtract 5x from both sides

4x = 60                         Divide by 4

4x/4 = 60/4

x = 15

Boys = 15

girls = 15 + 12 = 27

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
