    From LibreTexts, under not declared, as the source states it; its equations are written in TeX, which the PDF shows typeset. This page at LibreTexts.

    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
