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:
- Calculate \(-30 \times \frac{9}{5}\):
\[ -30 \times \frac{9}{5} = -\frac{30 \times 9}{5} = -\frac{270}{5} = -54 \]
- 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.
