Question

Using the formula for Fahrenheit and Celsius temperatures, F = 9/5 C + 32.

If the temperature is currently 25 degrees F. what is the temperature in C
degrees? Round to the nearest WHOLE number. LABEL

Answer 1

-4 degrees Celsius

Explanation:

F = 25

Substitute into formula: 25 = 9/5C + 32

subtract 32 from each side: -7 = 9/5C

multiply each side by the reciprocal of 9/5, which is 5/9

-7(5/9) = C

C = -35/9 which is close to -36/9 which is -4 degrees Celsius
