  5. Pre-Alg Quiz Part 1 and 2 Answers. Took the test. Their correct (KCA)
    Part 1:
    1. 7
    2. 8
    3. 7x + 5 = 4x + 5 3x
    4. B (If it's a graph thingy)
    5. k<0
    6. q <- -1
    7. p < 8
    8. g > 90
    and 9. n - 6 <- 2; n -> 8
    Part 2:
    1. Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.

    You have $59.95 in your wallet and want to buy some new CDs. If the CDs are $11.99 each, what number of CDs, x, can you buy? Write and solve an inequality.

    (If your made to write it out, here it is.)
    x - number of CD's,
    Inequality is,
    x · $11.99 ≤ $59.95
    x ≤ $59.95 : $11.99
    x ≤ 5
    So the actual answer would be is
    5 CD's
    (YOUR WELCOME) :)
