WILL MEDAL AND FAN The formula Q = MCT where Q = heat flow, M = mass, C = specific heat, and T = change of temperature is used to calculate heat flow. Solve this formula for T. T = Q – MC T = Q + MC T = QMC T = Q divided by the quantity M times C

    \(Q = MCT\) you want: \(T = something\) so you're gonna have to start dividing each side by something, right?

    no :( \(Q = MCT\) \(\frac{Q}{T} = \frac{MCT}{T} = \frac{MC}{1} = MC\) not that helpful, is it? you could try \(\frac{Q}{M} = \frac{MCT}{M} = \frac{CT}{1} = CT\) and do something very similar again

    " just a whole bunch of letters" the answer is supposed to be a whole bunch of letters :p and algebra is a whole bunch of letters too it's not easy so don't worry about it - but i cannot just do it for you. someone else might, or someone else might be better at explaining. i'd say go back and look at the bunch of letters and see where we got to just by doing the same thing to each side of the equals sign.

    we can start from the suggestion of @IrishBoy123 so we can write: \[\Large \frac{Q}{M} = CT\]

    now if we divide both sides of that above equation, by C, we get: \[\Large \frac{Q}{{MC}} = \frac{{CT}}{C}\] please simplify @briannam568

    on the RHS, you have C on the top and bottom of the fraction. what to do?

    you cross it out, since it is canceled out, right?

    ^Right \[\large \frac{Q}{MC} = \frac{\cancel{C}T}{\cancel{C}}\] So what do you have left?
