Answer:
F=70.7
Step-by-step explanation:
This is a simple substitution problem.
- The formula to change Fahrenheit to Celsius is [tex]F=\frac{9}{5}\left(C\right)+32[/tex].
- They give you C, so substitute it into the problem, which would give you [tex]F=\frac{9}{5}\left(21.5\right)+32[/tex].
- Simplify the right side of the equation by multiplying [tex]\frac{9}{5}[/tex] 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.
