What is the solution to -5m = -40?

8m would be the answer

Step-by-step explanation:

-5m/-5  = -40/5 = positive 8

We shall use a negative sign for an elevation below sea level, and a positive sign for an elevation above sea level.

Given:
Elevation of city A = -96 ft (below sea level)
Elevation of city C = -24 ft (below sea level)

Let x =  elevation of city D.

Part A.
Because the elevation of city D is 1/4 of the elevation of city C, therefore
x = (1/4)*(-24)

Part B.
Because 24/4 = 6, therefore
x  = -6 ft.


The elevation of city D is 6 feet below sea level.
The answer is negative because the elevation is below sea level.
