Answer 1

Correct answer is D

(-40°F − 32) × 5/9 = -40°C

Answer 2

Hi Ariana D.

 

Since

1.8C + 32 = F

(F - 32)/1.8 = C

You can determine where C and F are equal

Let C = F = x

x - 32 = 1.8 x

Solve for x

You can try the same with Kelvin, you can also look up the different temperature scales in your text or on the internet
