(a) Write out a correct rearrangement of the formula.

(c) A student was asked to rearrange the formula d 10a = - 2c(6 – d) to make d the subject (assuming that 1+ 14c + 0). The student's incorrect attempt is shown below. 10a =;-206-a) Clear the fractions By multiplying By 7 10 a = d-20lb-d) Multiply out the Bracket 10 a = d-12c-2cd Collect the d terms 10 a+12c = d– 2od Factorise 10 a +12c = dl - 20) Divide By I-20 to give 10 a +120 d = |-20
