I know how to simplify this equation (see attached photo), but I do not know how to find the restrictions (restricted values). If there was only one variable, like just x, I could do it, but I don’’t know how to solve when there are multiple variables. Does anyone have insight on how to find the restrictions in a multi-variable equation?

What is the value of x? enter your answer in the box. (cm)

Explain how you can find the missing fraction in 3 4/5 / (blank) 2 5/7. then find the missing fraction.

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.
