Answers:
24 quarters
22 nickels
==========================================================
Work Shown:
q = number of quarters
n = number of nickels
q+n = 46 coins total which solves to n = 46-q
25q = value of all the quarters in cents
5n = value of all the nickels in cents
25q+5n = value (cents) of all the coins of both types
25q+5n = 710 cents total = $7.10
-------------
Apply substitution.
25q+5n = 710
25q+5(46-q) = 710
25q+230-5q = 710
20q+230 = 710
20q = 710-230
20q = 480
q = 480/20
q = 24
They have 24 quarters
This yields 25*q = 25*24 = 600 cents = $6.00 so far.
Use that value of q to find n
n = 46-q
n = 46-24
n = 22
They also have 22 nickels.
They have an additional 5n = 5*22 = 110 cents = $1.10
In total, they have 6.00+1.10 = 7.10 dollars which confirms we have the correct coin counts. Also, q+n = 24+22 = 46.

Answer:
The ratio of green apples to red apples is 
.
Step-by-step explanation:
Given,
Number of red apples = 21
Number of green apples = 18
We have to find out the ratio of green apples to red apples.
Solution,
For finding the ratio we have to divide the number of green apples to the number of red apples.
So, we can frame the above sentence as;
Now substituting the values, we get;
Hence The ratio of green apples to red apples is .
