Question

use The fórmula to work out The temperatura in C when the temperatura is: 20° F 45°F 82°F​

Answer 1

Resposta:

$20F\\\frac{C}{5}= \frac{F-32}{9} \\\frac{C}{5}= \frac{20-32}{9}\\\frac{C}{5}= \frac{-12}{9}\\9c= -60\\c= \frac{-60}{9} \\c=-6,6$

$45F\\\frac{C}{5} =\frac{F-32}{9} \\\frac{C}{5} =\frac{45-32}{9} \\\frac{C}{5} =\frac{13}{9} \\9c=65\\c=\frac{65}{9} \\c=7,2$

$82F\\\frac{C}{5} =\frac{F-32}{9} \\\frac{C}{5} =\frac{82-32}{9} \\\frac{C}{5} =\frac{40}{9} \\9c=200\\c=\frac{200}{9} \\c=22,2$
