Answer:
9 nickels
Step-by-step explanation:
Set the number of pennies as x. The number of nickels would be 31 - x.
The pennies are worth x cents and the nickels are worth 5 * (31 - x), or 155-5x.
We are given that he has 67 cents, so:
x + 155 - 5x = 67
Solve.
-4x = 67 - 155 = -88
x = 22
Nickels are 31 - x, so the number of nickels he has is 9.
I hope this helps!

Answer: 2a+c
Step-by-step explanation: You add all variables that are positive then you subtract by negatives or vice versa. Add 3a+6a-7a yes subtract the 7a which gets you 2a. Add 8b+b-9b, you get 9b-9b which is 0 so you don’t need b in the problem anymore. -5a+4c+2c then you get c, because it is 1 c. So your answer is 2a+c. :P Hope this helped.
