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:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
