Answer:
10 Quarters
12 Dimes
Step-by-step
Let x = number of quarters (0.25)
22-x=number of dimes (0.10)
.25x +.10(22-x) = 3.70
.25x+2.2(-.10x) =3.70
<u>-.25x</u> <u>-.25 </u>
.15x -2.2=3.70
<u>-2.2</u> <u>-2.2</u>
<u />= x=10
So basically...
10 Quarters
22-10=12 So, 12 Dimes
Answer:
(0, 3)
Step-by-step explanation:

On the y-axis, every point has a 0 for the x-coordinate.
The ordered pair for the point that is 3 on the y-axis is (0, 3).
