Answer:
16
Step-by-step explanation:
If n is number of nickles and d is number of dimes:
5n + 10d = 440
n = 3.5d
Substitute:
5(3.5)d + 10d = 440
17.5d + 10d = 440
27.5d = 440
d = 16
9.108
You only need to look at the 10nths place to determine which number is larger
Answer: B. 53
5) 3x - 10 = x + 4

6) 6x + 4 = x - 11
answer: -3
3x - 10 = x + 4
x = 7
6x + 4 = x - 11
x = -3
