Answer: -15 C
Explanation:
This problem is worded a bit weird but let’s follow it along.
Our starting temperature is -5 C. We then know that the temperature “rises” at -18 C. Well clearly negative is not rising. We will combine these two to follow the verbiage. So -5 + -18 is -23 C.
It then states that the temperature falls at -8 C so we need to subtract-8 C from -23 C. So we have -23 - -8 = -23 + 8 = -15 C.
So our final temperature is -15 C.
Cheers.
