The formula Upper F equals nine fifths Upper C plus 32


changes a temperature reading from the Celsius scale C to the Fahrenheit scale F. What is the temperature measured in degrees Fahrenheit when the Celsius temperature is negative 30
degrees Upper C
​?

1 answer

To find the temperature in degrees Fahrenheit, we can substitute the given value of -30 degrees Celsius into the formula:

F = (9/5)C + 32

F = (9/5)(-30) + 32

F = -54 + 32

F = -22

Therefore, the temperature is -22 degrees Fahrenheit.
