Question

The low temperature last week was 13 Fahrenheit (F). What was the low temperature last week in degrees Celsius (C)? [C =59(F 32)]

Answer 1

The low temperature last week was of -10ºC.

Explanation:

The relation between temperatures in celsius(C) and Fahrenheit(F) is given by the following equation:

`F = (9C)/(5) + 32`

Here, we have that
`F = 13`, and we want to find C. So

`13 = (9C)/(5) + 32`

`(9C)/(5) = -19`

`9C = -90`

`C = - (90)/(9)`

`C = -10`

The low temperature last week was of -10ºC.
