Answer:

14 nickels
6 dimes

Step-by-step explanation:

The system of equations can be written ...

n + d = 20 . . . . . . . . coins in the jar

5n +10d = 130 . . . . . value in cents

_____

Using the first equation, we can write an expression for n:

n = 20 -d

We can substitute this into the second equation:

5(20 -d) +10d = 130

100 +5d = 130 . . . . . . simplify

5d = 30 . . . . . . . . . . . . subtract 100

d = 6 . . . . . . . . . . . . divide by 5

n = 20-d = 14

The jar contains 14 nickels and 6 dimes.

Hello There!

It is 1:12 for counselor to camper
If there are 156 campers, follow these steps:
