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...
22-10=12 So, 12 Dimes
Answer: 9
Step-by-step explanation:
Top:
8^(-1/3)
= (2^3)^(-1/3)
= 2^(-1)
Bottom:
36^(-1/2)
=(6^2)^(-1/2)
=6^-1
so
2^-1 / 6^-1
= 6^1 / 2^1
= 6/2
= 3
