Question

A cidade da Russia atingiu 14° F.Qual o valor dessa temperatura na escala Celcius ?

Answer 1

Tc/5 = (Tf-32)/9
Tc/5 = (14 -32)/9
Tc/5 = -18/9
Tc/5 = -2
Tc = -10ºC

Answer 2

 

$<var>\frac{Tc}{5} = \frac{Tf - 32}{9}</var>$

 

Tc = $<var>(\frac{14 - 32}{9}) .5</var>$

 

Tc = $<var>(\frac{-18}{9}) . 5</var>$

 

Tc = -2 . 5 = Tc = -10 C
