Answer:
42 Dimes, 10 Nickels.
Step-by-step explanation:
Dimes are worth $0.10, nickels are worth $0.05.
If D = number of dimes, and N = number of nickels, then the following equations are true:
0.10D + 0.05N = 4.70
D + N = 52
Next, let's multiply the first equation by 10 so that we can subtract the second one from it.
D + 0.50N = 47
(-) D + N = 52
Subtracting the second equation from the first one gives:
-0.5N = -5
-0.5N/-0.5 = -5/-0.5
N = 10
Finally, substitute N in the original second equation to find D.
D + 10 = 52
D + 10 - 10 = 52 - 10
D = 42
-45 + 150 = 105
Carol has $105 in her account after receiving her paycheck.
He did not walk 1/2 a mile. Because it's a round-trip, it's technically 2 miles long. so, in the end, he did not walk 1/4 of the trip. Hope this helps :)

Hi there.
First, let's round the 6:05 to 6:00 & add the 5 later.
The amount of time between 4:30 & 6 is 1 hour & 30 minutes.
1h 30m + 5m = 1h 35m
The elapsed time is 1 hour & 35 minutes.
