How would you solve these compound inequalities word problems?
1. The human ear can distinguish sounds between 20Hz and 20,000 Hz, inclusive.
2. For a man to box as a welterweight, he must weigh more than 140 lbs, but at most 147 lbs.

  • Math -

    The solution would simply be the statement of the inequality

    e.g. 2.

    if x is the number of lbs, then

    140 < x ≤ 147

    notice 140 is excluded , but 147 is included

    Do #1 the same way
