Answer:
48. Correct
49. Los Altos = 48
Westmoreland = -48
48 - ( -48)
48 + 48
96
The difference in elevation is 96 meters
50. Imperial = -18
Holtville = -3
(-18) ÷ (-3)
6
Imperial is 6 times as far below sea level than Holtville

I will go about solving this using the elimination method.
First, convert the equations.
10x + y = -20
4x + y = -12
Second, find the easiest variable to get rid of and get rid of it! (In this case, y) We will subtract to get rid of y.
6x = -8
Third, you want to solve the equation.
6x = -8 (divide by 6)
x =

Fourth, solve for y by inserting the answer for x into one of the equations.
10(

) + y = -20

+ y = -20 (subtract

)
y =

The solution for this system of equations is (

,

).
You multiple the area 18 x 12 = 96 sq ft
