me ajuda aí galera por favor ​e urgente ?

Answer 1

7.

a) 40/5 = (TF-32)/9 → 8 = (TF-32)/9 → TF-32 = 8•9 → TF-32 = 72 → TF = 72+32 → TF = 104

(104°F)

b) 100/5 = (TF-32)/9 → 20 = (TF-32)/9 → TF-32 = 20•9 → TF-32 = 180 → TF = 180+32 → TF = 212

(212°F)

c) TC/5 = (32-32)/9 → TC/5 = 0/9 → TC/5 = 0 → TC = 0•5 → TC = 0

(0°C)

d) TC/5 = (212-32)/9 → TC/5 = 180/9 → TC/5 = 20 → TC = 20•5 → TC = 100

(100°C)

e) 50/5 = (TF-32)/9 → 10 = (TF-32)/9 → TF-32 = 10•9 → TF-32 = 90 → TF = 90+32 → TF = 122

(122°F)
