The temperature on a certain morning is -11℃ at 5 a. m. If the temperature drops 3 degrees at 6 a.m. and rises 5 degrees at 8 a.m. and again drops 3 degrees at 9 a.m. What is the temperature at 9 a.m.?
-11 - 3 + 5 - 3 = ___
12 deggres Answer
12 degree celsius
12 degree
12 degrees Celsius
To find the temperature at 9 a.m., we need to follow the given information step by step.
First, the temperature at 5 a.m. is -11℃.
At 6 a.m., the temperature drops by 3 degrees. So, we subtract 3 from the previous temperature:
-11℃ - 3℃ = -14℃
Next, at 8 a.m., the temperature rises by 5 degrees. So, we add 5 to the previous temperature:
-14℃ + 5℃ = -9℃
Finally, at 9 a.m., the temperature drops again by 3 degrees. So, we subtract 3 from the previous temperature:
-9℃ - 3℃ = -12℃
Therefore, the temperature at 9 a.m. is -12℃.
