Wade wants to take his friends to the basketball game.  The tickets cost $10 each and snacks cost $15.  How many friends can he take to the game if he has no more than $85? Which inequality could be used to solve this problem?

• 10t + 15 ≥ 85
• 15s + 10 ≥ 85
• 10t - 15 ≥ 85
• 10t + 15 ≤ 85

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.
