Understanding Inequalities




               3. A savings account decreased by $50 is now less than $740.






               4. A number increased by 7 is at least 45.




               For the given value, state whether each inegquality is true or false.

               5.  18  < 9, c = 2                                 8. 10 - x < 3, x = 7
                   c






               6.  x   ≥ 3, x = 5                                 9. 11 + n < 32, n = 4
                   5






               7. 6k ≥ 42, k = 7                                  10. 9 + c > 19, c = 10








               Graph each inequality on a number line.

                 11. a < 6                       12. t ≥ -2                      13. d  ≤  3



                       4   5   6   7    8              -4  -3  -2  -1   0              1    2   3   4   5









               Write the inequality for each graph
                       14.                                                15.
