To determine which of the given inequalities is correct when x > 3, we need to evaluate each inequality.

Option A, 9x < 27

Given x > 3

x × 9 > 3 × 9 (multiple both sides by 9)

9x > 27

There is no need to flip the inequality sign because we performed multiplication by a positive number. So, this inequality is incorrect.

Option B, x + 7 < 10

Given x > 3

x + 7 > 3 + 7 (add 7 to both sides)

x + 7 > 10

There is no need to flip the inequality sign because we only performed addition. So, this inequality is inco...
