WTF? Simple problem.

  1. Jan 20, 2008 #1
    1. The problem statement, all variables and given/known data

    The relationship between degrees Farenheit and degree Celsius is given by the formula:

    [tex]\displaystyle{C = \frac{5}{9}(F - 32)}[/tex]

    For what temperature will degrees Celsius be 20 more than degrees farenheit?

    3. The attempt at a solution

    Is this the equation to solve???

    [tex]\displaystyle{\frac{5}{9}(F - 32) = F + 20}[/tex]

    Yes it is

    Celsius must be 20 degrees more than Farenheit, so [tex]C = F + 20[/tex] is the correct substitution.

    This is just wrong. at -40 the 2 scales are equal.

    What does that have to do with the question? No one is saying that "C= F+ 20" is generally true, just that it is true when "the degrees Celcius is 20 degrees more than Farenheit". C= F+ 20 is just a restatement of that.
