Answer:

The answer is 7 °C.

Explanation:

Using the formula given, we can see that we are inputting a Fahrenheit value to solve for a Celsius value. Therefore, we just need to plug it in to the formula.


45 = (9)/(5)C +32.

Now, we can subtract 32 from both sides to isolate
(9)/(5) C from the rest of the equation. This gives us
13 = (9)/(5) C.

Now, we just multiply by the reciprocal of the fraction in front of C to make it vanish and also apply that process to 13. Therefore, we do this:


(5)/(9) * 13 = 7.22222

Therefore, C ≈ 7° because of rounding requirements.
