20-4(4-3x)-7x=16-2(7-4x)

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

Ineed to know the answer to this algebra question.

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.
