2.7: Modeling with Equations
( \newcommand{\kernel}{\mathrm{null}\,}\)
Applications can be written as mathematical problems by identifying known quantities and assigning a variable to unknown quantities. There are many known formulas that can be used to solve applications. Distance problems are solved using the d = rt formula. Many geometry problems are solved using the perimeter formula P = 2L + 2W, the area formula A = LW, or the volume formula V = LWH. In this section you will review several types of Applications.
A linear equation can be used to solve for:
- Models and Applications
- Mixture and Uniform Motion Applications
A rational equation can be used to solve for
- Proportions, Similar figures and Variation
- Uniform Motion
- Work
