13. In the United States, we measure the temperature in degree Fahrenheit. However most of the other countries in the world use degrees Celsius. The formula for converting to Fahrenheit is given below.
a. Solve the formula F = 9/5C + 32 for C.

in order to convert Celsius to Fahrenheit, you will need to use this formula: F = 9/5C + 32. Therefore, you will need to solve for C or substitute values and solve in that manner. To find Fahrenheit temperature for -20 degrees Celsius, you can just plug it into the formula. Therefore, F = 9/5 (-20) + 32 and F = 28.4. If you were given 59 degrees Fahrenheit you would get: 59 = 9/5C + 32 and this would give you 27 (5/9) = C, after you have plugged the values into the above formula. When you simplify you, you get C = 15.
