Answer:
6 > 6 - a
3 < 3 + c
Step-by-step explanation:
Since you are told that there are less than six assignments, a represents what is taken away from the six. the result of 6 - a would be less than 6 itself.
Same concept can be connected with the other example. this time c is what you add to the 3 chores. The value of 3 + c will be greater than 3 itself
Hope this helps.
