7b divided by 12 = 4.2 what does b equal

14 is the best answer can i get brainliest?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Are you trying to figure out the volume?
