The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F. F = 9/5 C + 32 Which of the following formulas correctly solves for C? C = 5F - 32/9 C = 5F/9 - 32 C = 9/5 (F - 32) C = 5/9 (F - 32)

    When we solve for a variable we need to isolate that variable first. Isolate C Step one: do the opposite of addition which is subtraction. so we subtract -32 from both sides. |dw:1441763132933:dw|

    We divide both sides by 9/5 and we see that now 9/5 cancels out on one side

    Its easier in a way because I would look back and forth on it so I would figure it out how you did it because right now im confused like heck

    1 \[F = \frac{ 9 }{ 5 }C + 32 \] 2\[F-32 = \frac{ 9 }{ 5 }C\] 3 \[\frac{ 5 }{ 9 }(F-32) = C \]

    Step one I subtracted 32 from both sides, and i got F - 32 = 9/5c then I divided both sides by (9/5) when you divide a fraction you flip it the denominator becomes the numerator; so it becomes (5/9) and got (5/9)(F-32) = C

    @CIAsmart you have 9/5*C right? to take it away you do the opposite of multiplication which is division. so i divided both sides by (9/5) so on one side \[\frac{ 9/5 }{ 9/5 } C = C\] (9/5)/(9/5) = 1 then I did the same thing on the other side (F-32) \[\frac{ f-32 }{ \frac{ 9 }{ 5 } } = (5/9)*(f-32)\]

    it takes some time, though. there are people on this site who are much better than I am. \[\frac{ 1 }{ \frac{ 9 }{ 5 } } = \frac{ 5 }{ 9 }\] it's called the reciprocal it means we just put 1 over that number.
