MATH 1143 Idaho State University Algebra and Pre Calculus Questions

I need answers to my aleks homework which is a mix between algebra and pre calculus, I have to answer each question one by one before I can get access to the next question so it is a tedious process! There are 8 assignments with 3 answers needed each so 24 quesions!
