The equation (M )/84 = (p – 7)/21 relates two temperature scales, where M is the number of degrees on one scale and P is the number of degrees on the other scale. Which of the following equations can be used to convert temperatures from the P scale to the M scale?	Select the correct option:
A) (P-7)*6	B) (P-7)*5	C) (P-7)*2	D) (P-7)*3	E) (P-7)*4
M/84 =(P-7)/21   M = (P-7)*84/21   =(P-7)*4   (P-7)*4
