Question

A drama class has a total of 39 students. The number of males is 9 more than the number of females. How many males and how many females are in the class?

Answer 1

Answer:

15 females

24 males

Step-by-step explanation:

Given;

39 students total

9 more male student than female

1. Set up an equation

Call the number of female student "x"

Since there are 9 more male students, the number of male students is (x + 9),

Assuming those are the only genders in the class, the equation formed is;

females + males = total

x + x + 9 = 39

2. Solve,

Simplify and inverse operations;

x + x + 9 = 39

2x + 9 = 39

2x = 30

x = 15

15 females

24 males

Answer 2

Answer:

Step-by-step explanation:M+F=39

M+F=39

F=M-9

Substitute

M + M - 9 = 39

2M = 48

M=48/2

M=24

24+F=39

F=39-24=15

F=15, M=24
