Question

The sum of three consecutive even integers is 120. Find the largest of the three integers. I get 56.66 i am stuck!!!!

Answer 1

how did you get that answer?

Answer 2

It is very important to recognize wrong solutions. Is 56.66 an integer?

Answer 3

i got 39 now i am pretty sad huh lol

Answer 4

120= x + (x+2) + (x+4)
is the equation to use to solve this problem. Do you understand how I got that? And z must be an even integer, of course.

Answer 5

so the 3 intergers are 39 40 41?

Answer 6

Is 39 and even integer?

Answer 7

ok defining variable time

let "x" be equal to the largest even number

now for even consecutive numbers, the even number that comes before x would be x-2

and the even number that comes before x-2 would be x-4

add "x" "x-2" and "x-4" up and the sum of those are equal to 120

now solve for x

Answer 8

42?

Answer 9

38+40+42= 120
