The formula to change F to C is F equal 9/5 C + 32. If the temperature is 21.5 C what is it in F?

Umnica [9.8K]

Answer:

F=70.7

Step-by-step explanation:

This is a simple substitution problem.

The formula to change Fahrenheit to Celsius is $F=\frac{9}{5}\left(C\right)+32$ .
They give you C, so substitute it into the problem, which would give you $F=\frac{9}{5}\left(21.5\right)+32$ .
Simplify the right side of the equation by multiplying $\frac{9}{5}$ by 21.5.
Now, add 32 to 38.7, which should have been your answer to the previous step.
You should now have F= 70.7 as your answer.
