The statement below describes a situation in which opposite quantities combine to make 0. Is the statement true or false?

The temperature rises 15 degrees by noon and then rises 15 more degrees by 3 p.m

Answer 1

well if it rises 15 degrees each time , it will have rised 30 degrees throughout the day until 3:00 pm. but if you have 15 degrees and then add -15, which are different quantities, that woyld equal 0 like the first question.
