Kenny’s dog, charlie, is really smart! last week, charlie buried 7 bones in all. he buried them in 5 straight lines and put 3 bones in each line. how is this possible? sketch how charlie buried the bones.

Step-by-step explanation: It is possible if we consider lines horinzontally and vertically.

If there is a total of 7 bones and 3 straight lines are formed, it means that we have 2 straight lines in one direction and another one in another direction, using the same units.

It's very easy to see on the picture attached.
