Raquel collected 30 marbles

Step-by-step explanation:

If there are 80 marbles, and Raquel has collected 3/8 of them, he has collected 30

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

because they could drop even lower..
