Question

The following expression can be used to represent temperature in degrees Fahrenheit that is equivalent to -30 degrees Celsius.

(-30 x 9/5)

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

degrees Fahrenheit

Answer 1

To convert -30 degrees Celsius to degrees Fahrenheit, we can use the formula:

\[
F = \left( C \times \frac{9}{5} \right) + 32
\]

Where \( C \) is the temperature in degrees Celsius and \( F \) is the temperature in degrees Fahrenheit.

First, let's substitute -30 for \( C \):

\[
F = \left( -30 \times \frac{9}{5} \right) + 32
\]

Now simplify the expression step by step:

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 -54:

\[
F = -54 + 32 = -22
\]

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