I think he might be the only teacher in the world that could make a video about this particular problem that is 17 1/2 minutes in length lol.

37, 38, 81 in my head in about a minute.

37, 38, 81. The total has to be 156 in order for the average of three numbers to be 52.

[argonwheatbelly]

I think people forgot to multiply by 3, the number of numbers to be averaged.

[richardguglomo]

X= 37 so numbers are 37, 38, 81. Sum them and divide by 3 and you get average is 52

[dannyroosenboom]

the average od the 3 parts is 52 so the sum is 156. there is 4 times X plus 1 plus 7. suntract (1+7) from 156 and divide the resulp by 4 to get the value of X wich gives 37 so the numbers are 37 38 and 81
did the calculation by head so i maade a mistake in division in my original post

[danielcase]

fractions are exactly that. there is only one.
