Final answer:
Solving the inequality 512≥1.6x for x involves dividing both sides by 1.6 to isolate x, which results in the solution x ≤ 320. Among the given choices, x ≤ 845 is the correct statement.
Step-by-step explanation:
The inequality given is 512≥1.6x. To solve for x, we need to isolate x on one side of the inequality. We do this by dividing both sides of the inequality by 1.6:
512 ÷ 1.6 ≥ 1.6x ÷ 1.6
320 ≥ x
This can be rearranged to x ≤ 320. Thus, the correct answer from the options given is x ≤ 845, as it is the only option that is a true statement based on our solution.
