Santo's keychain us 1\4 of a foot long. How many inches long is the keychain?

3 inches

of a foot is 3 inches, because a foot is 12 inches.

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 : )
