Answer
-108.4 Fahrenheit
Work Step by Step
In order to complete this problem we must use the equation: C=$\frac{5}{9}$(F-32) to convert from Celsius to Fahrenheit.
Since the question tells us that the Celsius temperature in this problem is -78, we must plug that into our equation for C to get our answer. When we plug in -78 for C our equation looks like this:
-78=$\frac{5}{9}$(F-32)
The next step is to multiply both sides by $\frac{9}{5}$ to cancel out the $\frac{5}{9}$ on the right side of the equation, resulting in our new equation:
-140.4=F-32
Lastly, add 32 to both sides to get the answer:
F=-108.4
