Aiden has a collection of 63 nickels and quarters in
his piggy bank. If the total
value of the coins is $10.75,
how many nickels does
he have?

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 : )

rick would give her the best deal as he will charge $8.88 per hour

5050

hope this !
