  • Math -

    Deal with inequalities just like equations, except that you reverse the carats when multiplying or dividing by a negative number.

    Is there a typo in the first inequality?

    5-(3) < 10(-3)

    2 < -30 (That certainly is not true. Think of it in terms of money. Having $2 is not less than owing $30.)

    3 < 2x+1 < 9

    Subtract 1 from each part.

    2 < 2x < 8

    Divide each part by 2.

    1 < x < 4

    Use these principles in the remaining problems.
