Answer:
4a: 1
4b: 6, -6
Step-by-step explanation:
4a. (3 - 5)= -2; (9 - 6)=3
(-2 + 3) = 1
4b. We aren't told which cards Jesse pick up, only that they didn't affect his total points. Therefore, the two cards have the same number, but opposite signs. We coluld pick any teo an an example: 6 and -6, or 4 and -4, etc. They don't affect his score since they ccancel each other with a result of zero.
