Answer:

there are 20 girls in the band

Step-by-step explanation:

let number of boys= x

let number of girls = 10+x

so

x+10+x=30

2x=30-10

2x=20

x=20/2

x=10....

so if x= 10 then number of boys=10

number of girls=10+10=20....

Where to put the ( )’s 5+4+3 2=29
Salsk061 [2.6K]

Answer:

It all depends.

Step-by-step explanation:

It depends on what you are trying to do, and what you want to solve for. If you are trying to distribute the 3 into 2, you would place the parentheses around the 2. I hope I was able to help, but there is not much that I can do without more clear instructions!
