a) x ≤ 6
b) x ≥ 6
c) x ≤ 2
d) x ≥ 2

Answer 1

To solve the inequality 5x - 10 ≤ 20, add 10 to both sides and divide by 5. The correct answer is x ≤ 6.

Step-by-step explanation:

To solve the inequality 5x - 10 ≤ 20, we can start by adding 10 to both sides of the inequality equation, giving us 5x ≤ 30. Then, we divide both sides of the equation by 5, resulting in x ≤ 6. Therefore, the correct answer is option a) x ≤ 6.
