Transformar 4×39 F em graus Celsius

Answer 1

Transformar 4×39 F em graus Celsius

$\dfrac{TC}{5} =\dfrac{TF - 32}{9} \\\\\\ \dfrac{TC}{5} =\dfrac{(4\cdot39) - 32}{9} \\\\\\ \dfrac{TC}{5} =\dfrac{156 - 32}{9} \\\\\\ \dfrac{TC}{5} =\dfrac{124}{9} \\\\\\ 9TC = 5\cdot124 \\\\\\ 9TC = 620 \\\\\\ TC =\dfrac{620}{9} \\\\\\ TC = 68,8$


Resposta :

68,8 °C
