Answer:

Number of coins that are not nickels = 55 coins

66 = 55 + n

number of nickels in the​ jar = 11

Step-by-step explanation:

Pennies = 17

Dimes = 12

Quarters = 26

Nickels = n

Total coins = 66

How many of the coins are not​ nickels?

= Pennies + Dimes + Quarters

= 17 + 12 + 26

= 55 coins

Number of coins that are not nickels = 55 coins

what equation could you use to find​ n?

Total coins = Pennies + Dimes + Quarters + nickels

66 = 17 + 12 + 26 + n

66 = 55 + n

n = 66 - 55

n = 11

number of nickels in the​ jar = 11
