16 d) twice the difference of six times a number and seven The translation is 2 6n 7), and the simplified form is 2n Translate each of the following sentences into algebraic equations and solve to determine the numbers). Algebra must be used. a) The difference between five and twice a number is one. The translation is 5 2n, and the solution is n 2. b) Four less than three times a number is 25 The translation is 3n 4 25, and the solution is n 7. c) The sum of two numbers is eighteen. The total of three times the smaller and twice the larger is fortyfour. The translation, where the small number is s and the larger number is 8 s, is 3s s) 44, and the solution is s 8, so the two numbers are 8 and 0. d) Find two consecutive even integers such that four times the first is three times the second. The translation, where the two consecutive even integers are n and n + 2, is 4n 3 n + 2), and the solution is n 6, so the two consecutive even intergers are 6 and 8. e) The sum of two numbers is six. twenty. The sum of the squares of the two numbers is The translation, where the two numbers are n and 6 n, is n n) 2 20, and the solution is n 4 or n 2, so the two consecutive even intergers are 2 and The high temperatures for a 6day period in Barrow, Alaska, were 23 F, 29 F, 2 F, 28 F, 28 F, and 27 F. Calculate the average daily high temperature. Here the average is 23 F) + 29 F) + 2 F) + 28 F) + 28 F) + 27 F) 6 56 F 6 26 F. 25. The total cost to paint the inside of a house was $346. This cost included $25 for materials and $33 per hour for labor. How many hours of labor were required to paint the inside of the house? Algebra must be used. The translation, where h is the number of hours of labor, is h, and the solution is h 37, so 37 hours of labor were required. 6
17 26. A 2foot board is cut into two pieces. Twice the length of the shorter piece is 3 feet less than the length of the longer piece. Find the length of each piece. Algebra must be used. The translation, where the short piece is s feet and the long piece is 2 s, is 2s 2 s) 3, and the solution is s 3, so the lengths are 3 feet and 9 feet. 27. The perimeter of a rectangle is 26 meters. The length of the rectangle is meter more than twice the width. Find the length and width of the rectangle. Algebra must be used. The translation, where the width is w meters and the length piece is 2w +, is w + ) + 2w, and the solution is w 4, so the length and width are are 9 meters and 4 meters. 28. The perimeter of a triangle is 0 inches. One side is twice the second side. The third side is 30 inches more than the second side. Find the length of each side. Algebra must be used. The translation, where the length of the second side is x inches and the other sides 2x inches and x + 30 inches, is x + 2x + x + 30) 0, and the solution is x 20, so the lengths are 20 inches, 40 inches, and 50 inches. 29. The width of a rectangle is 5 feet less than the length. The area of the rectangle is 76 square feet. Find the length and width of the rectangle. Algebra must be used. The translation, where the length is l feet and the width is l 5 feet, is l l 5) 76, and the solution is l 6 or l 4, so the length and width are 6 feet and feet. 30. On a map, two cities are inches apart. If 3 8 inch on the map represents 25 miles, determine the number of miles between the two cities. First convert inches to an improper fraction mi in 3/8 in mi 7 25 mi 75 miles A car leaves a town traveling at 40 mph. Two hours later, a second car leaves the same town, on the same road, traveling at 60 mph. In how many hours will the second car pass the first car? Algebra must be used. The translation, where t represents the time, in hours, the second car has traveled when the two meet, is 60t 40 t + 2), and the solution is t 4, so it will take 4 hours. 4 The is an extraneous solution. 7
18 32. Two cars, one traveling 0 mph faster than the other, start at the same time from the same point and travel in opposite directions. In 3 hours they are 300 miles apart. Determine the rate of each car. Algebra must be used. The translation, where the rate of the slower car is r and the rate of the faster car is r + 0, in mies per hour, is 3r + 3 r + 0) 300, and the solution is r 45, rates are 45 mph and 55 mph. 33. The sales tax on a car that sold for $2,000 is $780. At this rate, how much higher is the sales tax on a car that sells for $3,500? The translation, where the length is x represents the additional tax paid, is x 3500, and the solution is x 97.50, so it will take $ more. 34. Graph the following lines on a Cartesian rectangular) coordinate system. a) y 2 3 x + Two points, such as 0, ) 3, ) should be used to plot the graph Figure : y 2 3 x + 8
19 b) x 2y 4 Two points, such as 0, 2) 4, 0) should be used to plot the graph Figure 2: x 2y 4 c) x 2 Two points, such as 2, 0) 2, ) should be used to plot the graph Figure 3: x 2 9
20 d) y 3 0 Two points, such as 0, 3), 3) should be used to plot the graph Figure 4: y
