Question

The formula to convert Celsius to Fahrenheit is F=9/5C+32. Convert 45°F to

Celsius. Round to the nearest degree.

Answer 1

About 7 degrees

Explanation:

`45=9/5C+32 \\\\13=9/5C \\\\C\approx 7`

Hope this helps!

Answer 2

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.
