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
Answer:
Hi, there I'll help you since no one helped you which I felt sad lol, but anyway here's your answer
x=2,y=7→ y=11-2x;4x-3y=-13
x=5,y=2→ 2x+y=12;x=9−2y
x=3,y=5→ y=10+x;-3x+3y=30
x=7,y=3→ x+3y=16;2x−y=11
Hope this helps :)
