    Week 4

    Problem #1
    Is the number shown in parentheses a solution for the given equation?
    x + 8= -12 (-6)

    No

    Problem #2
    Solve for x and check your result.
    10x = -100

    x = -100/10
    x = -10

    10 * (-10) = -100

    Problem #3
    Solve for x and check your result
    = 2

    x = 3 * 2
    x = 6

    6/3 = 2

    Problem #4
    Solve for x and check your result
    8- 5x = -7

    -5x = -8 - 7
    -5x = -15
    x = -15 / (-5)
    x = 3

    8 - 5 * 3 = 8 - 15 = -7

    Problem #5
    Solve the literal equation for the indicated variable
    K = (for m) Energy

    mv2 = K
    m = K/ v2

    Problem #6
    Solve the equation for x, and check your result:
    2(x + 3) = -6

    x + 3 = -6/2
    x + 3 = -3
    x = -3 -3
    x = -6

    2 * (-6 + 3) = 2 * (-3) = -6

    Problem #7
    Solve the equation for x, and check your result
    7(3x + 11) = 9(3 - 6x)

    21x + 77 = 27 - 54x
    21x +54x = 27 - 77
    75x = -50
    3x = -2
    x = -2/3

    7 ( 3 * (-2/3) + 11) = 9 (3 - 6 * (-2/3))
    7 * 9 = 9 * 7

    Problem #8
    Identify the indicated quantity in the statement
    The base in the statement "40% of 600 is 240."

    600 * 40/100 = 600 * 4/10 = 60 * 4 = 240

    Problem #9
    Carlotta received a monthly raise of $162.50. If this represented
    a 6.5% increase, what was her monthly salary before the raise?

    x * 6.5/100 = 162.5
    x = 162.5 / (6.5/100)
    = (162.5 * 100)/6.5
    = $2,500

    Problem #10
    Graph the solution of the follow inequality
    x < -2

    Shaded area is the graph.
