If a + b= 29, b + c = 45, a + c = 44
Find a + b + c = ?

a+b+c=59

Step-by-step 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

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
