Directions: I picked 3 dominoes out of a bag and they all had exactly 10 pips, but the same number was not on both sides of any of the dominoes.
Which dominoes could I have picked? Is there more than one answer?
If one side of the domino had 8 pips, how many pips were on the other side if I had 10 pips altogether?
If one side of the domino had __ pips, how many pips were on the other side if I had 10 pips altogether?
0 and 10
1 and 9
2 and 8
3 and 7
4 and 6
