InterAct math tutorials provide you with on-line practice problems and guided solutions.

Once you've practiced and mastered the basics of solving equations and inequalities, consider how you can use this skill in real-life situations. Refer back to page 465, the first page of Chapter 8 of your Developmental Mathematics textbook and review dimensions of a basketball court application.

Here's your chance to explore the World Wide Web and practice your new skills at the same time. Explore the official Web sites of the NBA and the WNBA to find and compare the official rules, including court dimensions, of these two professional basketball associations.

After you've practiced and explored, don't forget to prepare for your upcoming Chapter Test. Work through the Chapter 8 Review and then check your answers. These free downloadable files are accessible by selecting the Chapter Review button at the top of this page.

Good luck!
