65	If y is an integer, then the least possible value of \|23 - 5y\| is
66	$$\sqrt{80}+\sqrt{125}=$$
67	y=kx+3In the equation above, k is a constant. If y = 17 when x = 2, what is the value of y when x = 4 ?

69	Al and Ben are drivers for SD Trucking Company. One snowy day, Ben left SD at 8:00 a.m. heading east and Al left SD at 11:00 a.m. heading west. At a particular time later that day, the dispatcher retrieved data from SD`s vehicle tracking system. The data showed that, up to that time, Al had averaged 40 miles per hour and Ben had averaged 20 miles per hour. It also showed that Al and Ben had driven a combined total of 240 miles. At what time did the dispatcher retrieve data from the vehicle tracking system?
70	Of the land owned by a farmer, 90 percent was cleared for planting. Of the cleared land, 40 percent was planted with soybeans and 50 percent of the cleared land was planted with wheat. If the remaining 720 acres of cleared land was planted with corn, how many acres did the farmer own?
71	At the start of an experiment, a certain population consisted of 3 animals. At the end of each month after the start of the experiment, the population size was double its size at the beginning of that month. Which of the following represents the population size at the end of 10 months?
72	If $$(\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+\frac{1}{6}) = r(\frac{1}{9}+\frac{1}{12}+\frac{1}{15}+\frac{1}{18})$$, then r =
73	If x and y are positive integers such that y is a multiple of 5 and 3x + 4y = 200,then x must be a multiple of which of the following?
74	Which of the following expressions can be written as an integer?(1) $$(\sqrt{82}+\sqrt{82})^{2}$$(2) $$({82})(\sqrt{82})$$(3) $$\frac{(\sqrt{82})(\sqrt{82})}{82}$$
75	Four staff members at a certain company worked on a project. The amounts of time that the four staff members worked on the project were in the ratio 2 to 3 to 5 to 6. If one of the four staff members worked on the project for 30 hours, which of the following CANNOT be the total number of hours that the four staff members worked on the project?
76	Pumping alone at their respective constant rates, one inlet pipe fills an empty tank to $$\frac{1}{2}$$ of capacity in 3 hours and a second inlet pipe fills the same empty tank to $$\frac{2}{3}$$ of capacity in 6 hours. How many hours will it take both pipes, pumping simultaneously at their respective constant rates, to fill the empty tank to capacity?
77	In the xy-coordinate plane, which of the following points must lie on the line kx + 3y = 6 for every possible value of k?
78	If $${x}^{2}-{2}<{0}$$, which of the following specifies all the possible values of x ?
79	Shawana made a schedule for reading books during 4 weeks (28 days) of her summer vacation. She has checked out 12 books from the library. The number of pages in each book and the order in which she plans to read the books are shown in the table above. She will read exactly 50 pages each day. The only exception will be that she will never begin the next book on the same day that she finishes the previous one, and therefore on some days she may read fewer than 50 pages. At the end of the 28th day, how many books will Shawana have finished?
