Please answer, and you of course don't have to answer number two <3

1.) You need to have the original temperature and the final temperature.

2.)

3.) The temperature decreased by 17 degrees between the early afternoon and the following morning.

We know the original temperature to be 10 degrees and the final temperature to be -7 degrees. To find the change in temperature we subtract the initial temperature from the final temperature -7 - 10 = -17. The question asks by how many degrees did the temperature drop. It is asking for the magnitude of the difference, so the answer is the above sentence.
