Ray Brock · Answer 1

So in Fahrenheit temp, the the car is protected between - 22 F and 266 F

Mendez · Answer 2

C = 5/9 (F - 32)

C = - 30

-30 = 5/9 (F - 32)

-30 = 5/9F - 160/9

-30 + 160/9 = 5/9F

-270/9 + 160/9 = 5/9F

-110/9 = 5/9F

-110/9 * 9/5 = F

- 990/45 = F

- 22 = F

C = 5/9 (F - 32)

C = 130

130 = 5/9F - 160/9

130 + 160/9 = 5/9F

1170/9 + 160/9 = 5/9F

1330/9 = 5/9F

1330/9 * 9/5 = F

11970/45 = F

266 = F

So in Fahrenheit temp, the the car is protected between - 22 F and 266 F
