Answer:
Explanation:
Start (*C) Change(*C) Final Temperature (*C)
a -20 30 degrees warmer 10
b -20 35 degrees warmer 15
c -20 15 degrees warmer -5
d -20 15 degrees colder -35
Number line diagrams:
a. Starting from -20C, a 30 degrees warmer temperature change takes the final temperature to 10C.
-40 -30 -20 -10 0 10
-------->
b. Starting from -20C, a 35 degrees warmer temperature change takes the final temperature to 15C.
-40 -30 -20 -10 0 10 20
----------->
c. Starting from -20C, a 15 degrees warmer temperature change takes the final temperature to -5C.
-40 -30 -20 -10 0 10
------->
d. Starting from -20C, a 15 degrees colder temperature change takes the final temperature to -35C.
-40 -30 -20 -10 0 10 20 30 40
