-4
Step-by-step explanation:
-22-(6)(-9)/3
= -22 -(6) (-3)

= -4
To solve this problem, you can use a simple table to find the number of quarters and dimes:
type of coin I Quantity of coin I Value of coin (in amount of money)
------------------------------------------------------------------------------------------------------
dimes I x I 10x (a dime is equal to 10 cents)
------------------------------------------------------------------------------------------------------
quarters I 18-x I 450-25x (a quarter is equal to 25 cents)
After doing this table, you can form the equation:
10x + 450 - 25x = 420
-15x = -30
x = 2 dimes
18-x = 16 quarters
