Question

converta para Celsius os seguintes valores:
a) TF= 40°F
b) TF= 122°F
c) TF= 77°F

Answer 1

Olá Thauane,
Como vai?
Vamos lá:

$\boxed{\boxed{\frac{T_{C}}{5}=\frac{T_{F-32}}{9}}}$

$a)\\ \\ \frac{T_{C}}{5}=\frac{40-32}{9}\\ \\ 9T_{C}=5*8\\ \\ T_{C}=\frac{40}{9}\\ \\ \boxed{T_{C}=4,44\°C}$

$b)\\ \\ \frac{T_{C}}{5}=\frac{122-32}{9}\\ \\ 9T_{C}=5*90\\ \\ T_{C}=\frac{450}{9}\\ \\ \boxed{T_{C}=50\°C}$

$\frac{T_{C}}{5}=\frac{77-32}{9}\\ \\ 9T_{C}=5*45\\ \\ T_{C}=\frac{225}{9}\\ \\ \boxed{T_{C}=25\°C}$

Espero ter ajudado (:
