  2. I might be forgetting something or then I'm just being stupid.. How would you find the answer to |n|<6 1/4? I read through the sections but I couldn't find help :(

  3. How would you simplify an expression like -3y+21?

  4. For |n|<6 1/4 ... use our alternative language!

    The distance that n is from zero is less than 6 1/4.... Where can 'n' live such that it is less than 6 1/4 units from zero?

    Look up (IN YOUR NOTES, OF COURSE!) your definition for a simplified expression... and you'll see "mission accomplished!"

  6. oh for #47 I just showed both versions of the problem like n<61/4 and n>-61/4... Is that right?

  7. Is it -6 1/4<n<6 1/4
    ???
    And I like your dragon, Mr.C! ;)

  8. An "AND" compound inequality can be written in either shorthand form:

    -6 1/4-61/4

    Both are correct although 4 out of 5 algebra teachers surveyed prefer the shorthand method.

    Please remember that "OR" compound inequalities must be written separately.
