What is the temperature an object can reach that will be the same in Celsius and in Fahrenheit ?

Question

C=5(F-32)/9

Answer 1

from ur question...
C=5/9(F-32)
C=F

answer.
F=5/9F-160/9
4/9F=-160/9
4F=-160
F= -40
the answer is -40

Answer 2

The equation you listed is the relationship between a Fahrenheit temperature, represented by "F," and the corresponding Celsius (or centigrade) temperature, "C."

C = 5(F-32)/9

We want to find the value where F and C are the same -- in other words, F=C. But since F=C, any place we see the C variable, we can replace it with (or "substitute") the F. That gives us:

F = 5(F-32)/9

Now we just have to solve this for F. We start by multiplying both sides by 9:

9F = 5(F-32)

Using the distributive property on the right-hand side,

9F = 5F - 160

Subtracting 5F from both sides gives

4F = -160

And, finally, we divide both sides by 4:

F = -40

And since C = F, C = -40, too.

Let's test our answer. The original equation was:

C = 5(F-32)/9

If we evaluate this equation when C = -40 and F = -40, do we get a true statement? Let's find out:

-40 = 5(-40-32)/9

We simplify inside the parentheses first: -40-32 = -72

-40 = 5(-72)/9

Next, 5*(-72) = -360

-40 = -360/9

And -360/9 = -40

-40 = -40

That's certainly a true statement, which means we found a correct solution.

Hope that helps!

Answer 3

-40 C = -40 F

Answer 4

hey its more of a quiz question & it has become very common

we generally use tis formula,and coz the temp is same in celcius as well as farenheit we can replace c by f or vice versa

(f-32) = 9c/5
f-32= 9f/5
-32= 9f/5 - 5f/5
-32= 4f/5
-32*(5/4)=f
-40=f

Answer 5

Answer 7

Answer 8
