Given t > 0 and a < b, to determine which inequalities is not correct, we need to analyze each one:

Option A, a + t > a

Adding a positive number t to a will always result in a number greater than a. So, this inequality is correct.

Option B, at > bt

Give t > 0 and a < b, multiplying both sides of a < b by t (a positive number) will preserve the direction of the inequality: at < bt. So, this inequality is not correct....
