Nasir bought a piece of wood with a length less than 5 feet. Which inequality represents this situation?

Solve the inequality 5x - 8 ≤ 27.

• x ≥ 7

• x = 27

• x ≤ 7

• x ≤ 5

What would be the first step in solving the inequality for 2x+7>15?

• Add 7 to both sides

• Subtract 7 from both sides

• Divide both sides by 2

• Multiply both sides by 2
