Answer 1

efetue as conversoes solicitadas:

b) -40 C em F

$\dfrac{TC}{5} =\dfrac{TF - 32}{9} \\\\ \dfrac{(-40)}{5} =\dfrac{TF - 32}{9} \\\\ (-8)\cdot9 = (TF - 32) \\\\ -72 = (TF - 32) \\\\ -72 + 32 = TF \\\\ TF = -72 + 32 \\\\ TF = -40$

Resposta : -40 °F

Answer 2

vamos lá!


5f-160=9.c

5f-160=9.(-40)

5f-160=-360


5f=-360+160

5f=-200

f=-200/5

f=-40°F

espero ter ajudado!


boa tarde!
