what do you need help with
The answer is B because every time Nelson mows a lawn, he will earn $15 each.
200m - 100m + 48,250 = 50,250 - 150m
(Add or subtract common variables)
100m + 48,250 = 50,250 - 150m
(Add 150m to both sides)
250m + 48,250 = 50,250
(Subtract 48,250 to both sides)
250m = 2000
(Divide 250 to both sides to isolate m)
m = 8
Answer: $65.50 - 15% = 55.675
Step-by-step explanation:
Conversion a decimal number to a fraction: 65.50 = 655
10
= 131
2
Conversion a decimal number to a fraction: 9.825 = 9825
1000
= 393
40
Subtract: 65.5 - 9.825 = 131
2
- 393
40
= 131 · 20
2 · 20
- 393
40
= 2620
40
- 393
40
= 2620 - 393
40
= 2227
40
The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 40) = 40
