the average weight of 6 is 61 pounds. If three of the crates weigh 72, 59, and 70 pounds, respectively, which of the following could be the weights, in pounds, of the other three crates?

Average weight = total weight / # of items = total weight / 6
total weight = 366 lbs.
So 366 - 72 - 59 -70 = 165 lbs
The remaining three crates will weigh a combined 165 lbs.
or an average of 55 lbs ( 165 lbs / 3 )

the other 3 crates all weigh 55 pounds..
add 72+70+59+55+55+55 = 366
366/6 = 61

55 each or 63, 50 and 52
-----------------------------------------
6 x 61 = 366
366 - 72 - 59 - 70 = 165
165 / 3 = 55

You ought to speak to your tutor - obviously you don't know a thing on this subject and having everyone answer your questions is not teaching you anything. Stop cheating! You are only cheating yourself!
