Answer:
75
Step-by-step explanation:
48% of snowstorms caused power outages, which means 52% did not.
Therefore, 39 is 52% of all snowstorms.
39 = 0.52x
x = 75
There were 75 snowstorms over the 5-year period.
It would be -(-31) because a negative and negative is a positive
It would be 8 + 40 because you multiply the 4 by the 2 and 10
