Question

numa das regiões mais frias do mundo , o termometro indica -76°F . qual esse valor na escala celsius?

Answer 1

$\frac{T_c}{5} = \frac{T_f-32}{9}\\\\\ \frac{T_c}{5} = \frac{-76-32}{9}\\\\\ T_c = \frac{-108*5}{9}\\\\\ T_c = \frac{-540}{9}\\\\\ \boxed{T_c = -60\ C\°}$

Answer 2

TF=1,8*Tc+32
-76=1,8*Tc+32
1,8*Tc+32=-76
1,8*Tc=-76-32
1,8Tc=-108
Tc=-108/1,8
Tc=-60° C
