Answer:
a+b+c=59
Explanation:
a+b=29
b+c=45
a+c=44
Therefore we know that a and b are each equal to less than 29. And c must be equal to less than 44. By messing around with those numbers I got that if a is equal to 14 and b is equal to 15, that gives us 29. And if b is equal to 15, then 15 minus 45 is equal to 30. Meaning that c would equal 30. And if we add c + a, or 30+14, that is equal to 44. So then a+b+c=? can be written as 14+15+30=59
