The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To convert Celsius temperature to Fahrenheit temperature, the formula is C = 5 over 9 (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car.

so the equation C=5/9 (F-32) is the formula to find Celsius when we have Fahrenheit, so we need to rearrange it to F=C(9/5)+32
then sub both Celsius values in the formula
F=-30 (9/5)+32
=-22
F=130 (9/5)+32
=266
to the antifreeze protects the car between -22°F and 266°F

Answer:

-22°F and 266°F
