Question

What must be the temperature in
Fahrenheit so that it will be twice its
value in Celsius?
(Ans. 320 °F)​

Answer 1

Answer:

Explanation:

320 degrees Fahrenheit.

We know that Fahrenheit, F = 9/5C + 32, where 'C' is for Celsius scale.

We have 2C = F for the given problem.

Just place F in the formula with 2C that gives us 2C = 9/5C + 32.

When we subtract 9/5C from both sides, it will give 2C - 9/5C = 32.

Now, just simplify the left side of the equation, (2C = 10/5C): 10/5C - 9/5C = 32, that is equal to 1/5C = 32.

Now, multiply 5 to either side, which provides us with C = 160.

And, we know that F = 2C, therefore the answer is 320 degrees Fahrenheit.
