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.

u got this @supie or me

supie · Answer

ight so first the equation is   C=5/9 (F-32 to find the Celcius  when we got F  so we gotta change it to F=C(9/5)+32 and then subtract both Celc. F=-30 (9/5)+32
=-22
F=130 (9/5)+32
=266
so it would be between -22°F and 266°F i think

darkknight · Answer

yes, u are correct, @supie
so yeah when you write your inequality it will be 
−22°F≤x≤266°F

Where x is a Fahrenheit temperature at which this antifreeze protects the car.
