Question

The following expression can be used to represent temperature in degrees Fahrenheit that is equivalent to -30 degrees Celsius.
(-30 x 9/5) + 32

Simplify the expression to determine the temperature in degrees Fahrenheit that is equivalent to -30 degrees Celsius.

degrees Fahrenheit

Answer 1

To simplify the expression \((-30 \times \frac{9}{5}) + 32\), we can follow these steps:

1. Calculate \(-30 \times \frac{9}{5}\):

\[
-30 \times \frac{9}{5} = -\frac{30 \times 9}{5} = -\frac{270}{5} = -54
\]

2. Now, add 32 to the result:

\[
-54 + 32 = -22
\]

Thus, the temperature in degrees Fahrenheit that is equivalent to -30 degrees Celsius is \(-22\) degrees Fahrenheit.
