Question

Quest.: 3 3. Se a temperatura é 20. ˚C, qual é a temperatura correspondente na escala Fahrenheit?

Answer 1

formula = c/5 = f -32/9

20/5 = f-32/9

4 = f-32/9

4 x 9 = f-32

36 = f-32

36+32 = f

f = 68°f

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
