Seventy-two people signed up for the soccer league.  After the players were evenly divided into teams, there were 6 teams in the league and x people on each team. Which equation represents this situation?

• 6 + x = 72
• 72x = 6
• 6x = 72
• x - 6 = 72

The low temperature was 35⁰F. This was 13⁰F lower than the daytime high temperature.  Write an equation to determine whether the high temperature was 48⁰F or 42⁰F.

• x - 13⁰F = 35⁰F  x=48⁰F
• x + 13⁰F = 35⁰F  x=48⁰F
• x - 13⁰F = 35⁰F  x=42⁰F
• x + 13⁰F = 35⁰F  x=42⁰F
