Question

A problem states: "There are 5 more girls than boys at the party. There are 27 children at the

party in all. How many boys are there at the party?"
Let b represent the number of boys.
Which expression represents the number of girls?
B-5
B+5
Bx5
5-b

Answer 1

The expression that represent the number of girls is (b+5)

Explanation:

Let

b -----> the number of boys

g ----> the number of girls

we know that

`b+g=27` -----> equation A

`g=b+5` -----> equation B

substitute the equation B in equation A and solve for b

`b+b+5=27`

`b+b=27-5`

`2b=22`

`b=11\ boys`

Find the value of g

`g=11+5=16\ girls`

therefore

The expression that represent the number of girls is (b+5)
