Kate has 21 coins (nickels and dimes) in her purse. how many nickels and dimes does she have if she has $1.50? a. 3 nickels and 18 dimes b. 5 nickels and 16 dimes c. 12 nickels and 9 dimes d. 15 nickels and 6 dimes

C. 12 nickels and 9 dimes.

This is the only one that adds up to 1.50

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 : )
