Answer:
To figure out the change, we subtract the original temperature by the following after temperature.
18°F - original
-9°F - subsequent time after original
So we set up the equation;
18°F - (-9°F)
(Two negatives combine to form a positive)
18°F + 9°F
= <u>27°F</u> was the change in temperature.

Step-by-step explanation:
This one sounds the most confident, being a call to action. It is good to end a thought with motion.
x=1 and x=-1/3
Therefore, x=1 and x=-1/3
the answer is will be $140
