A number plus 1 is greater than -5 and less than three.
define a variable, write an inequality.

Inequality: -5 < X + 1 < 3
Variable: -6 < X < 2

Hope this helps. :)

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
