Aleah represents two unknown integers as a and x. She knows their product is greater than 25. She wants to know more about x. Can you write a single inequality to solve ax>25 for x? Explain.
A. No, because inequalities can only contain one variable, not two.
B. Yes. Since the product is greater 25, then either both α and x are positive or both are negative. Therefore the direction of the inequality will not change when dividing both sides of the inequality by a: x> 25/a .
C. Yes. Divide both sides of the inequality by a and switch the direction of the inequality: x<25/a.
D. No, the unknown integer, a , could be a positive or negative integer, so you cannot be sure which symbol o use in the solution.
