-15+n=-9
+15 +15
__________
n=6

What i did basically was add 15 on both sides, then -15 crosses out because it is added by +15 so they are additive inverses so they get crossed out. Then we have -9+15 and - +=-. So 15 - 9=6. So ur answer is 6. You can even do a check.

-15+n=9
-15+6=9
9=9 which proves that our answer is correct.

For this case we can model the problem as a rectangle triangle.
We have:
Length of the sides of the triangle.
We want to find:
Length of the hypotenuse.
Using the Pythagorean theorem we have:
$d ^ 2 = 2 ^ 2 + 2 ^ 2
$
$d = \sqrt{2 ^ 2 + 2 ^ 2} 

d = \sqrt{4 + 4} 

d = \sqrt{8} 

d = 2\sqrt{2} 
$
Answer:
She is:
$d = 2\sqrt{2}$
miles far from her starting point
