The formula $f = \frac{9}{5} c + 32$ can be used to convert temperatures between degrees fahrenheit ($f$) and degrees celsius ($c$). how many degrees are in the celsius equivalent of $-22^\circ f$?

-30° C

Explanation:

Data provided in the problem:

The formula for conversion as:

F  = (9/5)C + 32

Now,

for the values of F = -22 , C = ?

Substituting the value of F in the above formula, we get

-22 = (9/5)C + 32

or

-22 - 32 = (9/5)C

or

(9/5)C = - 54

or

C = - 54 × (5/9)

or

C = - 30 °

Hence, -22 Fahrenheit equals to -30°C
