Sally is cutting 80 inches of ribbon for a craft project. The second piece of ribbon is twice the length of the first. The third piece of ribbon is 5 inches shorter than the first. Which equation could represent this situation?

• 2x + (x - 5) = 80
• x + 2x + (x - 5) = 80
• x + x + (x - 10) = 80
• x + 2x + (x + 5) = 80
