Write Remember Define the term literal equation in Literal equations can be rewritten using properties of equality your own words. to allow you to solve for one specific variable. Practice 1. In the USA, the shoe sizes for men are approximated by the equation 3f - s = 24, where f represents the length of the foot in inches and s represents the shoe size. a. The average man's foot is 11.5 inches long. What is the average man's shoe size? b. Use the function to determine the x- and y-intercept. State the meaning of each in terms of this problem situation. c. Which form can most easily be used to determine the slope of this equation? Determine the slope of this equation and describe what it means in terms of the problem situation. 2. The boxes that shoes come in are often used in other capacities once the shopper has bought the shoes. Sometimes the boxes are used to hold other items, so it is helpful to know the volume of the box. a. Write the equation to solve for the volume of the shoe box. b. If the area of the base of the box is 112 square inches and the height is 3.5 inches, what is the volume of the box? c. Rewrite the equation to solve for width. Show your work. d. A box has a volume of 456 cubic inches, with a length of 1 foot and a height of 4 inches. Determine the width of the box. 3. Solve each equation for the specified variable. a. V = =Bh for B b. I = prt for r C. x+y 3 = 6 for y d. A + B + C= 180 for C
