Complete question :
In the evening, the temperature is 2828 degrees. By midnight it has dropped 3131 degrees lower. Between midnight and 4 am, it goes down 66 more degrees. Then, by 9 am, the temperature goes up 3030 degrees. Find the final temperature.
Answer:
-38°
Step-by-step explanation:
Evening temperature = 28°
By midnight = 31° lower
4am = 66° lower
9 a.m = 30° higher
Temperature at midnight :
28° - 31° = - 2°
Temperature at 4 a.m:
-2° - 66° = - 68°
Final temperature at 9a.m :
-68° + 30° = - 38°
The temperature at 9a.m is - 38°
