Question

Temperatura de 87°F. Determine na escala celsius​

Answer 1

$\boxed{\dfrac{T_C}{5}=\dfrac{T_F-32}{9}=\dfrac{T_K-273}{5}}$

$T_F=87\ºF\ \therefore\ \dfrac{T_C}{5}=\dfrac{87-32}{9}=\dfrac{55}{9}\ \therefore\\\\ T_C=\dfrac{5(55)}{9}\ \therefore\ T_C=\dfrac{275}{9}\ \therefore\ \boxed{T_C\approx30.56\ºC}$
