Answer:
900 miles
Step-by-step explanation:
Well, 200 miles is 1 inch. 100 miles is 1/2 an inch.
I agree with what that person told you. The expression -2(x+10) is equivalent to -2x-20
Multiply the outer -2 with the inner x to get -2 times x = -2x
Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20
So overall, -2(x+10) = -2x-20
--------------------------------------------
So that's how we're able to go from this

to this

The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.
1,000 I guess I don't really understand the question

17X-7Y. You add or subtract the same variables, in this case you only have two x's and one y. So you add them, because you have a addition sign. 13x+4x and you leave the Y alone, because there is not another Y variable.
