Answer 1

Hi, Kacie.

So, if the number of students(s) is decreased by 6, the remainder is equal to twice the number of boys(b) in the class.

Let's write that as an equation:

s - 6 = 2(b)

So, if the number of students is 44, then:

44 - 6 = 2(b)

38 = 2b

19 = b

So there are 19 boys in the class. If you subtract that from the total number of students (44) , then

44 - 19 = 25 girls

There are 25 girls in the class.
