Answer:

35 x (-4x) = -1           (9 hours)

Step-by-step explanation:

If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.

35 x (-4x) = -1

-4x = -36

x =  9
