Answer:
There are 18 dimes and 12 quarters
Step-by-step explanation:
Remember that
1 Dime =$0.10
1 Quarter=$0.25
Let
x-----> the number of dimes
y-----> the number of quarters
we know that
x+y=30
x=30-y ------> equation A
0.10x+0.25y=4.80
Multiply by 100 both sides
10x+25y=480 ------> equation B
Substitute equation A in equation B and solve for y
10(30-y)+25y=480
300-10y+25y=480
15y=180
y=12 quarters
Find the value of x
x=30-y=30-12=18 dimes
therefore
There are 18 dimes and 12 quarters
18u^2. For verifying that count the entire squares of the triangle, and use the partial one to make complete squares.
