Final answer:
To solve the inequality 5d > 5 - d, add d to both sides, then divide both sides by 6 to isolate d. The correct answer is d > 6.
Step-by-step explanation:
To solve the inequality 5d > 5 - d, we can start by adding d to both sides of the inequality, which gives us 6d > 5. Then, we can divide both sides of the inequality by 6 to isolate d, giving us d > 5/6. Therefore, option C, d > 6, is the correct answer.
