------------------------------------------------ The formula to convert Celsius to Fahrenheit is [tex]F = \frac{9}{5}C + 32[/tex]. Convert 45°F to Celsius. Round to the nearest degree.

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.

[tex]45 = \frac{9}{5}C +32[/tex].

Now, we can subtract 32 from both sides to isolate [tex]\frac{9}{5} C[/tex] from the rest of the equation. This gives us [tex]13 = \frac{9}{5} C[/tex].

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:

[tex]\frac{5}{9} * 13 = 7.22222[/tex]

Therefore, C ≈ 7° because of rounding requirements.
