The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To convert Celsius temperature to
Sveta_85 [38]

we know that

C = \frac{5}{9}(F-32)\\ \\F=\frac{9}{5}C+32

Step 1

<u>Find the inequality</u>

we know that

C = \frac{5}{9}(F-32) --------> equation 1

and

-30\° < C < 130\°

substitute the equation 1 in the inequality

-30\° < \frac{5}{9}(F-32) < 130\°

Step 2

<u>Convert -30\°C to F</u>

substitute in the formula

F=\frac{9}{5}*(-30)+32\\ \\F= -22\°

Step 3

<u>Convert 130\°C to F</u>

substitute in the formula

F=\frac{9}{5}*(130)+32\\ \\F= 266\°

therefore

-22\° < F < 266\°

the answer is the option

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