Answer:
17
Step-by-step explanation:
The expression of interest is the difference of the two given expressions.
(-4x +6y) -(-2x -7y) = (9) -(-8)
-2x +13y = 17
The value is 17.

<em>Additional comment</em>
You could go to the trouble to solve the two equations for x and y, then compute the value of the expression you want. As we saw above, that is not necessary.
The first step in problem solving is always "look at the given information and how it relates to what you are asked." A little time spent doing that can save a lot of effort in the actual problem solving process.

Answer:
1320m^3
Step-by-step explanation:
Volume of a prism = Area x Cross Section
Area of a triangle = 1/2 x base x height
Cross section in this figure = 11m
Volume of triangular prism = 1/2 x 16 x 15 x 11
Volume = 1320m^3
I hope this helps you!! If you need more explaining, I'll be happy to add to my answer.
Lets round each distance to the nearest tens place, and then add them up to get an estimate. 143 rounds down to 140, 138 rounds up to 140, and 141 rounds down to 140. So: 140 + 140 + 140 = 420 miles
