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

Answer:

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

Step-by-step 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)
