Let
n-------> the number of nickels
q------> the number of quarters
we know that
so
----> equation A
----> equation B
substitute equation B in equation A
Find the value of q
therefore
<u>The answer part a) is</u>
the number of nickels are and the number of quarters are
<u>the answer Part b) is</u>
The expressions that represents the number of quarters is
So you subtract 180 from 90 you get you answer then you will divide it by 55 and your remaining answer which you will get will be x
