R = recycling and reuse industry jobs
w = waste management jobs
we know, those two jobs combined are 1,275,000
or
r + w = 1,275,000
we also know that, whatever the "w" jobs are, are really less than "r"
jobs by 1,025,000
"r" has 1,025,000 more than "w"
or
r = w + 1,025,000
or
r-w = 1,025,000
so... there, just solve by elimination, simple, notice the "w",
is just waiting to be eliminated :)

The distance between the points (d) is found using the Pythagorean theorem.
Imagine the two points as defining the hypotenuse of a right triangle. The lengths of the legs of the triangle are the horizontal distance between the points and the vertical distance between the points. The the theorem tells us
d² = 4² + 7²
d² = 16 + 49
d² = 65
d = √65 ≈ 8.1
The distance between the points is
C 8.1
_____
You know that the distance must be longer than the longest leg (7) and must be shorter than the sum of the two legs (4+7=11). The only answer choice between 7 and 11 is 8.1.
