Question

A jar contains only​ pennies, nickels,​ dimes, and quarters. There are 29 ​pennies, 13 ​dimes, and 21 quarters. The rest of the coins are nickels. There are 91 coins in all. How many of the coins are not​ nickels? If n represents the number of nickels in the​ jar, what equation could you use to find​ n?

Answer 1

Answer:

First Question: 63 coins are not nickels.

Second Question: 63+n=91

Step-by-step explanation:

For your first question: 29+21=50 and 50+13=63. 63 coins are not nickels.

For your second question: You can do 29+21+13+n=91, I just simplified and said 63+n=91. You can choose.

Hope that this helps! Good luck with what you're working on!

Answer 2

Answer:

63 coins are not nickels.

Equation to find n:

91 - 63

Or

91 - n
