Answer:
20
Step-by-step explanation:
The answer will be 20 because you are doubling from both sides.
You have to go 3 squares to the left (staying in the x coordinate of 0) and after that you go 2 squares up. Hope this helps. :)
Equations:
m = k + 5
k = s + 2
m + k + s = 30
-----------------------
Substitute for "m" and for "s"::
k+5 + k + k-2 = 30
3k +3 = 30
3k = 27
