Answer: Let's say the first number is x, the next one is x+1, and so on
Step-by-step explanation:
x + (x + 1) + (x + 2) = -51
x + x + 1 + x + 2 = -51
3x + 3 = -51
3x = -54
x = -18
So the first step is to subtract 4.00 from 20.50. Once we do that, we get 16.50. The next step is to divide 16.50 by 2.75, to find out how many miles (after the 1st mile) Sarah's ride was. 16.50/2.75 = 6. So 6 + 1 = 7. The total mileage length to get to the movies was 7 miles.
They can walk 1.5 to 2.0 miles
