QS = 11x - 57
since r is the midpoint, QR + RS = QS
4*4*4*x*x*x*y*z*z (the * is multiplication)
The correct answer is this one: "b.) 1/12." <span>Makoto and his friends rolled 2 fair number cubes 500 times & recorded the sum of the numbers shown on the cubes each time.

So here it is:
1/12 42/250 = .083 1/12-.084.
There are 36 possibilities of rolls and three of them total 10.
3/36=1/12.
