Answer: 31
Step-by-step explanation:
Note that it is given that the three integers are consecutive, meaning that when represented by x, you have 3 integers: x, x+1, and x+2.
Then you use the fact that the sum of the three integers is 90:
x + x+1 + x+2 = 90
3x + 3 = 90
3x = 87
x = 29
Now notice that the question is asking for the largest integer, not x. So the answer is 31.
