The point P, Q, R and S lie int hat order on a straight line. The midpoint of QS is R and the midpoint of PS is Q. The length of QR is x feet and the length of PQ is 4x-16 feet. What is the length, in feet, of PS? How do you know?

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

i think it would be 42cm

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
