1: Solve \(\frac{1}{3} t - 5 < t - 2 \le -3t + 7.\)Give your answer as an interval.

 

It is not (t/3-3,-3t+9)

 

2:Jeri finds a pile of money with at least $200. If she puts $50 of the pile in her left pocket, gives away 2/3 of the rest of the pile, and then puts the rest in her right pocket, she'll have more money than if she instead gave away $200 of the original pile and kept the rest. What are the possible values of the number of dollars in the original pile of money? (Give your answer as an interval.)

 

It is not [200,575),[200,275),(200,275),(200,275]

 

3:Find a linear inequality with the following solution set. Each grid line represents one unit.

 

The line is dotted and has the equation y=1x+1. They are asking you to find everything to the right of that line.(the lline is dotted).


(Give your answer in the form or where and are integers with no common factor greater than 1.)

 

Thnk You In Advance!

1)  Break this up into two statements:  (1/3)t - 5  <  t - 2        and        t - 2  <=  -3t + 7

      Solve each one:                                  t - 15  <  3t - 6                         4t  <=  9

                                                                      -2t  <  9                                 t  <=  2.25

                                                                         t  >  -4.5  

      As an interval:  (-4.5, 2.25]
