Question

A science class has a total of 48 students. The number of males is 10 more than the number of females. How many males and how many females are in the class?

Answer 1

There are 19 females and 29 males.

Explanation:

Total = 48

x = number of females

y = number of males = x + 10

x + y = 48

y = x + 10

x + (x + 10) = 48

2x + 10 = 48

2x = 38

x = 19

Substitute x back in the first two equations

x = number of females = 19

y = number of males = 19 + 10 = 29

There are 19 females and 29 males.
