  1. Circle the equations that are always true for all values of a, b, & c:
    a + b = b + a (a + b) / c = (a/c) + (b/c) a + (b + c) = (a + b) + c a·b = b·a
    a - (b + c) = a - b + c a·(b + c) = a·b + c a·(b + c) = a·b + a·c a - (b - c) = a - b - c
    (a ÷ b) ÷ c = a ÷ b ÷ c a ÷ (b ÷ c) = (a ÷ b) ÷ c a + (b × c) = (a + b) × c a ÷ (b/c) = a × c/b
  2. Evaluate:
    1. 10 - 3 • 7 + 52 ÷ 13 - 32 + 2 • 6 + 8 ÷ 2
    2. 4 - 3 • 7 + 5 - 32 + 2 • 6 + 8 ÷ 2
  3. Solve:
    1. 5x + 3 = 3 - 7x
    2. 3x - 4 = 6 - 2x
    3. 5x - 2 = 2 + 5x
    4. 7x - 13 = -13 + 7x
    5. x/3 + x/4 + x/8 = 51
    6. 3.1x - 5.3 = 2.7 - 4.9x
  4. If a television costs $108.00 after a 40% discount, what was the original price?
  5. To convert from degrees Celsius to Fahrenheit, use this formula:  F = (9/5)·C + 32

    B. If the temperature is -40 °F, then what is the temperature in degrees Celsius?
  6. Sound travels at 5 seconds per mile. At how many miles per hour does sound travel?
  7. The number of games, N, that a soccer league of n teams plays in one season is:
    N = n × (n - 1)
    A. How many games will a league of 8 teams play?
    B. By adding one more team, how many more games will be played in that league?
  8. The wattage, W, that an electrical device uses is calculated as the voltage, V, times the amperage, A. That is, W = V · A. If you were given the wattage and voltage, what is the amperage? In other words, solve for A.
  9. What percent of 60 is 12?

  11. 27 is 20% of what?
  12. If the sales tax in New York City is 10%, and Holly goes to Tiffany's with only a $100 bill, what is the most that she can buy before sales tax?
