Ok so you would just take the two fractions and simply if needed and that the answer!
Answer:
-1
Step-by-step explanation:
The common difference is the constant amount of change between the numbers in an arithmetic sequence.
To find the common difference, you take the last term and subtract it by the previous term.
![\frac{-3}{2} - \frac{-1}{2} =-1](https://tex.z-dn.net/?f=%5Cfrac%7B-3%7D%7B2%7D%20-%20%5Cfrac%7B-1%7D%7B2%7D%20%3D-1)
45 - 2t < 32 ( where t is time and you can replace it with x or h if you prefer)
Solving for t you get:
45 - 2t - 32 < 0
45 - 32 < 2t
13 < 2t
13/2 < t
Or the temperature will drop below 32F after 6 and a half hours
The answer is C
You find this by dividing Y by X
