Answer:
B
Explanation:
First, let's figure out what our two numbers are.
-7/2 = -3 1/2.
So if we have -2 + -3 1/2, that means we must first travel -2 units, which will be the first blue arrow, then add -3 1/2 more units. This would give us an answer of -5 1/2 units.
That means B is the answer, because it's the only one that ends up at -5 1/2.
