G -7.3 degrees Celsius
H-15.1 degrees Celsius
J-6.3 degrees Celsius

Answer 1

Answer: (G) -7.3 degrees Celsius

Explanation:

To find the temperature at midnight, we need to start with the temperature at 8 P.M. and then add or subtract the temperature changes that occurred between 8 P.M. and midnight.

The temperature change between 8 P.M. and 10 P.M. was +3.9 degrees Celsius, so the temperature at 10 P.M. was:

-6.8 + 3.9 = -2.9 degrees Celsius

The temperature change between 10 P.M. and midnight was -4.4 degrees Celsius, so the temperature at midnight was:

-2.9 - 4.4 = -7.3 degrees Celsius
