Answer:

Step-by-step explanation:
Isolate x on one side of the equation.
x+11-11=3-11 (Subtract 11 from both sides.)
3-11 (Solve & Simplify.)
3-11=-8
X=-8

So, the correct answer is x=-8.
You need to select two points on the line:
The rise is the vertical distance, and the run is the horizontal distance:
Rise: Use the coordinates in y to find the rise:

Run: Use the coordinates in x to find the run:

The slope (m) is: 1/2 or 0.5
X - shorter piece
3x - 2 - longer piece
x + 3x -2 = 18
x + 3x = 18 +2
4x = 20 | : 4
x=5
3*5 -2 = 15 - 2 = 13
shorter piece: 5 ft
longer piece : 13 ft

Answer:
The elevation of Mt. Wilson is 16,160.10 ft
Step-by-step explanation:
Let
x-----> represent the elevation of Mt. Wilson
y ----> represent the elevation of Snow Crest
we know that
y=x+11,990.21 ----> linear equation that represent this situation
we have that
y=28,150.31 ft ----> see the attached figure
substitute in the linear equation and solve for x
28,150.31=x+11,990.21
x=28,150.31-11,990.21=16,160.10 ft
