b) greg drove 130 miles in 2 hours and 325 miles in 5 hours.
c) eliza sold 8 candy bars for $16 and 15 candy bars for $30.
d) lewis packed 60 pears in 5 boxes and 112 pears in 9 boxes.

It would be B because it’s the only answer that cannot be divided or multiplied evenly

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
