This lesson on solving linear equations with applications covers a range of word problems, including geometry, age, mixture, money, rate-time-distance, and percent. The tutor walks through how to solve these problems step by step, including how to convert units of measurement and repeating decimals to fractions. The lesson concludes with a check to ensure the solution is correct using the rate-times-time-equals-distance formula.
[NOTE: This video is only a 12 minute portion of the full 3 hour lesson. Please visit my website to purchase complete version] This lesson consists of providing you with a Self-Tutorial on how to solve typical linear word problems (story problems or applied problems). The tutor shows you how to solve for a specific variable in formulas. He also discusses how to covert a repeating decimal into a fraction (which was skipped in Basic Math: Lesson 6 -\"Fractions\") and will teach you how to convert units of measurement.
Examples of word problems done include:
Finding a number based on certain criteria.
Word problems involving some geometry (triangle, rectangle, circle).
Age problems.
Mixture problems.
Money problems (story of my life!).
Rate-Time-Distance problems.
Percent Equations/problems.
Ratio and Proportion (concepts and solving problems, including similar triangles).
Problems dealing with Unit Price.
