Question

a temperatura de uma sala de aula e 20 *C. qual será a leitura na escala fahrenheit?

Answer 1

TC÷5=(TF-32)÷9
20÷5=(TF-32)÷9
4=(TF-32)=9
9X4=(TF-32)
36+32=TF
TF=68 

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
