(b) Suppose that 2x +y= 5 and x + 2y= 7. What is the average of and y?
(c) The average of t2, 2t and 3 is 9.If t <0, determine the value of t.
答案解析
(a) If Q(5,3) is the midpoint of the line segment withendpoints P(1,p)and R(r,5),what are the values of p and r?
(b)A line with slope 3 and another line with slope -1 intersect at P(3,6). What is the distance between the x-intercepts of the two lines?
(c) For some value of t, the line with equation y=tx+t is perpendicular to the line with equation y=2x+ 7. Determine the point of intersection of these two lines.
答案解析
(a) The positive divisors of 6 are 1, 2, 3, and 6. What is the sum of the positive divisors of 64?
(b) Fionn wrote 4 consecutive integers on a whiteboard.Lexi came along and erased one of the integers. Fionn noticed that the sum of the remaining integers was 847. What integer did Lexi erase?
(c) An arithmetic sequence with 7 terms has first term d2 and common difference d. The sum of the 7 terms in the sequence is 756. Determine all possible values of d.
(An arithmetic sequence is a sequence in which each term after the first is obtained from the previous term by adding a constant, called the common difference. For example, 3,5,7,9 are the first four terms of an arithmetic sequence.)

根據(jù)歐幾里得歷年考試及分?jǐn)?shù)線情況的數(shù)據(jù)，可以得出以下結(jié)論：
要獲得前25%的成績(jī)，通常需要得到70分左右，只需正確回答7至8道題目即可獲得證書(shū)；
如果想晉級(jí)前5%，則需要至少順利完成9道題目，成績(jī)線通常在85分左右；
想要獲得頂級(jí)成績(jī)，需要保持在95分以上，且需要攻克高難度問(wèn)題。
歐幾里得數(shù)學(xué)競(jìng)賽考試結(jié)束后，一般會(huì)在3個(gè)星期后在CEMC官網(wǎng)公布考分成績(jī)。(獲獎(jiǎng)證書(shū)也差不多會(huì)在這個(gè)時(shí)間段寄出)
