Question

A quantos graus fahrentheit correspondem -5?
​

Answer 1

Se for -5°C:

TC ÷ 5 = (TF - 32) ÷ 9, sendo: TC = -5

* -5 ÷ 5 = -1 *, logo:

-1 = (TF - 32) ÷ 9

-9 = TF - 32

TF = -9 + 32

TF = 23°F

Se for -5K:

TC = K - 273

TC = -5 - 273

TC = -278

TC ÷ 5 = (TF - 32) ÷ 9, sendo: TC = -278

(-278) ÷ 5 = (TF - 32) ÷ 9

-2502 = 5TF - 160

5TF = (-2502) ÷ 160

5TF = -15,6375

TF = (-15,6305) ÷ 5

TF = 3,1275°F
