求问几道gre数学题
1.Yesturday the average number of cars per hour that passed point P was 34 between 1:00p.m.and 8:00p.m.and was x between 2:00p.m.and 7:00p.m.问x与34比较大小.
这道题不是34/8-1=x/7-2么.
2.a>b,c>d,a>c,问b和d的关系（为啥不是b〉d?）
3.x>0,问根号下x与根号下x^2比较大小
4.请问这句英文是什么意思：The sum of 30 and the number of five-dollar bills in the cash register.
5.请问一个圆圈里有个叉,题干是：For all real numbers x and y,x圆圈叉y=x^2-y^2,问14圆圈叉15与15圆圈叉14比较大小
