Scholar #2 is correct. You take 15=-3m-18+5m-7 and combie like terms. Which will leave you with 15=2m-25. You will simplify from there, getting 20=m.
The geometric mean of 2 & 200 is *(20)*
1) 300miles X $0.20 = $60
2) $50 + $60 = $110
They spent $110 for the car.
Step-by-step explanation:
3 : x = -7.5
5 : x = -10
6 : x = 12
