triangle a b c is shown. the length of a c is 28, the length of c b is 24, and the length of a b is 16.
triangle d e f is shown. the length of e f is 20. angle f d e is 34 degrees and angle d e f is 108 degrees.
triangle g h j is shown. the length of g h is 17 and the length of g j is 22. angle h j g is 47 degrees.

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
