Answer:
The solution would be (6, 2)
Step-by-step explanation:
In order to solve this using elimination, simply add the two equations together.
2x + 3y = 18
3x - 3y = 12
-----------------
5x = 30
x = 6
And now that we have the value for x, we can solve for y.
2x + 3y = 18
2(6) + 3y = 18
12 + 3y = 18
3y = 6
y = 2
To convert from inches to kilometers, we need a conversion factor to relate the two units involved in the problem. <span>We
either multiply or divide this certain value to the original measurement
depending on what is asked. For this case, we use 1 meter is equal to 39.37 inches and 1000 meter is equal to 1 kilometer. We do as follows:
</span><span>3.44 x 108 inches ( 1 meter / 39.37 inches ) ( 1 kilometer / 1000 meter ) = 8737.62 kilometers</span>

Answer:
The angle of elevation is about 27°
Step-by-step explanation:
Let's view this case in the form of a right angled triangle. With the original height as the opposite side to the elevation angle and the shadow length as the adjacent side.
Let x represent the original height
2x is the length of shadow
And θ the angle of elevation
Applying trigonometry;
Tan θ = opposite/adjacent = original height/shadow length
Substituting the values;
Tan θ = x/2x
Tan θ = 1/2
θ = taninverse(1/2)
θ = 26.56505117707
θ ≈ 27°
Elevation angle is approximately 27°
