The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To convert Fahrenheit temperature to Celsius 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.

The antifreeze protects the car between -40°F and 257°F

Step-by-step explanation:

Inequalities

The range of Celsius temperatures the car's antifreeze protects the car is

To convert °C to °F we use the formula:

To find the equivalent range of temperatures in °F, substitute the formula:

Multiply by 9, divide by 5:

Operating:

Adding 32:

Operating, we get the range of temperatures in °F:

The antifreeze protects the car between -40°F and 257°F
