On the 1st pic only do number 9! Please do asap for both!

#9: 10.5

Step-by-step explanation:

128 / 12

(Only did #9 because I don't have enough brain power to do the other one, hope you find someone else to do that.)

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 : )
