SOMEBODY PLEASE HELP ME. Mary is planning to provide online math and French tutoring sessions. The math sessions will be 30 minutes long and the French sessions will be 45 minutes long. She plans to work no more than 30 hours per week and does not want to provide more than 20 French sessions in any one week. Let M represent the number of math sessions and F represent the number of French sessions that Mary will offer during the week. Which system of inequalities represents the constraints of the given situation?
