Question

A que temperatura un termómetro Fahrenheit marca numéricamente el doble que el centígrado

Answer 1

ºC = ºF - 32
`````  ``````````
 5        9

 2X(EL DOBLE) =  X - 32
 ````                      ````````````
 5                              9

18 X = 5 X - 160

18X - 5 X = -160
13X = - 160

X = -12.30 º

2X = -12.30

ºC = -24.60
````````````````````````````````````````````````````````````

ºC = ºF - 32
         ````````
             1.8

2x(1.8) = x - 32

3.6x = x - 32

3.6x - x = - 32

2.6 x = -32

x = -12.30º

2x = -12.30º

ºC = 2(-12.30) = -24.60ºC

Answer 2

Respuesta:

A -40

ºC = ( ºF - 32 ) / 1.8

ºC = ( -40 - 32 ) / 1.8 = -40ºC

ºF = ( ºC x 1.8 ) + 32

ºF = ( -40 x 1.8 ) + 32 = -40 ºF

-40 ºC = - 40 ºF
