36 is the answer. Hope this helped!
The slope of line A is m= 1/3
Answer:
x+3
Step-by-step explanation:
If you factor 5 out of the denominator of the first expression, 5x+15 turns into 5(x+3).
Then, since you have x+3 in the numerator and denominator, it will cancel out.
The steps are shown below:

Ive attached an image that shows an example of simplifying an expression using a the same technique.
(3x+1) + (2x+8) = 180
5x+9=180
5x=171
(2,-1) is the correct pair I hoped this helped :)
this is because east is two to your right and south is one down
