Answer:
<u>13 Quarters and 18 Dimes</u>
Step-by-step explanation:
Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). Give x and y a break, and make it easier to remember which is which.
D + Q = 31
D = Q + 5
Therefore:
D + Q = 31
(Q+5) + Q = 31
2Q + 5 = 31
2Q = 26
<u>Q = 13</u>
<u>Then D = (13+5) or 18</u>
================
Check:
D + Q = 31 ?
18 + 13 = 31 <u>YES</u>
----------------------
D = Q + 5 ?
18 = 13 + 5 <u>YES</u>

20
Step-by-step explanation:
Maya has 120 caramel apples to sell.
Each caramel apple is covered with one topping.
1/5 of the caramel apples are covered with peanuts.
1/3 of the caramel apples are covered with chocolate chips.
3/10 of the caramel apples are covered with coconut.
The rest are covered with sprinkles.
find:
How many caramel apples are covered with sprinkles?
120 = (1/5 * 120) + (1/3 * 120) + (3/10 * 120) + sprinkles
120 = 24 + 40 + 36 + sprinkles
sprinkles = 120 - 24 - 40 - 36 = 20
therefore,
there are 20 caramel apples covered with sprinkles.
