Question

The label on the car's antifreeze container claims to protect the car between -30C and 130C. 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

Answer 1

-22 ≤ temperature(F) ≤ 266

Explanation:

Given that,

The label on the car's antifreeze container claims to protect the car between -30C and 130C.

Formula to convert Celsius temperature to Fahrenheit

C = 5/9 (F - 32)

9C/5 = (F - 32)

9C/5 + 32 = F

F = 9C/5 + 32

1)

-30C = ?F

F =9(-30)/5 + 32

F = -22

2)

130C = ?F

F =9(130)/5 + 32

F = 266

The inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car is

-22 ≤ temperature(F) ≤ 266
