The label on the cars antifreeze container claims to protect the car between-30'c and 130'c. to convert celsius temperature to fahrenheit temperature, the formula is c' =5/9 (f-32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car.

−30 < 5 over 9 (F − 32) < 130; −22 < F < 266

Step-by-step explanation:

Suppose F represents the temperature in degree Fahrenheit at which the antifreeze container protects the car,

Since, to convert Celsius temperature to Fahrenheit temperature, the formula is,

According to the question,

C' must be between -30°C and 130°C,

⇒ -30 < C' < -130  ------(1)

Now,

Thus, -30° in degree  Fahrenheit =

Also, 130° in degree Fahrenheit, =

Hence, we can write,

−22 < F < 266
