Answer:
B
Step-by-step explanation:
150s or 2 min and 30 s
20 facts = 1 min
10 facts = 30s
50 facts = ? min
50 / 10 = 5
30 * 5 = 150s
150s = 2 min and 30 s
you need to solve for x
the ez way for me is by flipping it so now it is -(7-10)=x and 10 -7=3
Option C is the answer.
At least, I think so.
Looks like it's already answered
