    Solve: -4x < .8
    Solution: Using the Multiplication Principle, multiply both
    sides of the inequality by -.25. Then reverse the
    signs.

    -.25(-4x) > -.25(.8)

    x > -.2

    Wow you lost me. So how would that work with a fraction, do you still do it by -.25?

    If 3X - 1 = 11, what is the value of X^2 + X?

  • Mike's Question - ,

    -7x > 1/15
    divide both sides by -7, remembering to reverse the inequality sign
    x < -1/105
