Question

C=5/9(F−32)
The equations above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?

I. A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 5/9 degrees Celsius.

II. A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.

III. A temperature increase of 5/9 degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.

A. I only.

B. II only.

C. III only.

D. I and II only.

Answer 1

Hello

Answer 2

Let's take a look at case 1 first

We increase the temperature in Fahrenheit by 1, will the temperature in Celsius change by 5/9?

let's see
C=5/9(F−32)

Let's first say that we have 32 Fahrenheit
what would you get?

C = 5/9 (32- 32)
C = ?

Answer 3

While I wait and hope that your silence doesn't mean you're confused, @KynxKatz , I shall proceed a little bit further

And after you calculate that, let's use 33 Fahrenheit. So that way we can test option 1. What happens when we increase the temperature by 1 F

So we have

C = 5/9 (33-32)
C = ??

Is the difference between the first answer and this one 5/9?

If so, that makes condition 1 true
