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 = (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car. −30 (F − 32) 130; −22 F 266 −30

Question

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 = (F − 32). Write and solve the inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car. −30 > (F − 32) > 130; −22 > F > 266 −30 < (F − 32) < 130; −22 < F < 266 −30 < (F − 32); −22 < F (F − 32) < 130; F < 266
