Question

transformar 20 graus Celsius em Fahrenheit

C = F -32 sobre
5 4

Answer 1

20 °C → ? °F

Tc / 5 = Tf - 32 / 9

20 / 5 = Tf - 32 / 9

4 = Tf - 32 / 9

4 · 9 = Tf - 32

36 = Tf - 32

36 + 32 = Tf

68 °F = Tf

Answer 2

Boa tarde!

_________________________

TC/5=TF-32/9

20/5=TF-32/9

4/1=TF-32/9

36=TF-32

-TF=-32-36

-TF=-68 (-1)

T=68°f
