°F -> °C
alguém pfv?
a) 59 °F -> °C

b) 77 °F-> °C

c)95 °F -> °C

d) 113 °F -> °C

e) 104 °F -> °C

Answer 1

 a) C÷5=F-32÷9
C÷5=59-32÷9
C÷5=27÷9
9C=135
C=135÷9
C=15°C


b)C÷5=77-32÷9
C÷5=45÷9
9C=225
C=225÷9
C=25°C

d)C÷5=95-32÷9
C÷5=63÷9
9C=315
C=315÷9
C=35°C


e)C÷5=104-32÷9
C÷5=72÷9
9C=360
C=360÷9
C=40°C

Answer 2

a)59ºF

Tc = Tf - 32 
5         9

Tc = 59 - 32 
5           9

Tc = 27
 5     9 

Tc = 3 
5

Tc=3*5

Tc=15ºC

b) 77 °F

Tc = Tf - 32
5          9

Tc = 45
5       9

Tc=5*5

Tc=25ºC


d) 113 °F

Tc = Tf - 32
 5         9

Tc=113 - 32
5        9

Tc = 81
5      9

Tc=9*5

Tc=45ºC

e) 104 °F
Tc = Tf - 32 
5          9

Tc = 104 - 32
5         9

Tc= 72
 5    9

Tc=8*5

Tc=40ºC.
