Yes :-)
3/10 = 30/100 or 30%
I think it’s C. Sorry if I’m incorrect
So are you trying to simplify one side to get it to look like the other?
Answer:
there are 9 quarters and 19 dimes
Step-by-step explanation:
Let x be the number of dimes and y the number of quarters
-dimes: 0.1x
-quarters: 0.25y
-the total amount of coins : x + y = 28
=> x = 28 - y
We have the equation:
0.25y + 0.1x = 4.15
0.25y + 0.1(28 - y) = 4.15
0.25y + 2.8 - 0.1y = 4.15
0.15y = 1.35
y = 9
x = 28 - y
= 28 - 9
= 19
Answer:
B
Step-by-step explanation:
All functions have y with a power of 1.
option B. is the only one where y has a power of 1.
