2. 56/（3/4-2/5）=1603. 3/(20%*2-25%)=20

1、①Thank you for helping me with my math . ②He had never seen creature such a strange looking. ③She yelled at him tiddalik and right up to marches. ④kangaroo did somersaults to make tiddalik laugh ⑤I told you about he is the man.2、（1）解：依题意得未看56页,已看是全书的2/5（因为已看比未看的2:3,全书有5份 ） 解设：全书为x. 3/4x-2/5x=56 x=160(2)蓝蓝折了x只[1-(1-25%)]x-3=(1-20%)xx=60

① 在马拉松比赛中，60个选手中有42个完成了比赛。有百分之几的选手没有完成比赛？ (60-42)/60 = 0.3答案—— 30 Percent (%) ② 两个连续的正整数的积是132，他们的和是多少？ x(x+1) = 132x^2 + x -132 = 0(x-11)(x+12) = 0x = 11, x = -12 因为是正整数，所以 x = 11，x+1 = 12 11 + 12 = 23 答案——23 twenty-three

英语1 Thank you for helping me with my math 4 i told about you the man he is数学1 设已看2X页书则这本书有5X页 2X+56=5X（3/4） X=32 5X=32x5=160 答：这本书有160页 2 设蓝蓝折了X只，则天天折了（1-25%）X只 X-20%X=（1-25%）X+20%X-3 4/5X=15X+4X-60 3X=60 X=20 20-25%x20=15 答：天天折了15只，蓝蓝折了20只。 估计楼上那位不会吧~~

The little red and jack Bauer and mutually leave home and do, little red every minute walk 52 meters per minute, jack Bauer walked 70 meters, two people in A place of meeting. If the little red four minutes in advance, and the speed of the same, jack Bauer every minute walked 90 meters, the two people who still in A place to meet, little red and jack Bauer home how many meters apart?小红和小强同时从家里出发相向而行,小红每分钟走52米,小强每分钟走70米,两人在途中的A处相遇.若小红提前4分钟出发,且速度不变,小强每分钟走90米,则两人仍在A处相遇,小红和小强的家相距多少米?A: are 1464 meters apartWith the second yuan A equation set, A place with little red house apart X m, little red house and jack Bauer home Y m, are: 1. X = (Y divided by 52-X) divided by 70, 2. (52)-4 X divided by = = (Y-X) divided by 90 reduction can get: 122 X = 52 Y, 142 X-52 Y = 18720 solution binary A equation can get: X = 624, Y = 1464答： 相距1464米用二元一次方程解，设A处与小红家相距X米，小红家和小强家相距Y米，可得：1. X除以52=（Y-X）除以70， 2. （X除以52） -4==（Y-X）除以90 化简可得：122X=52Y， 142X-52Y=18720 解二元一次方程可得：X=624，Y=1464 A b two people at the same time from the runway at and do it, after six minutes, two people to meet according to walk, four minutes after the start point b a return to the starting point and 300 m distance, and the runway.甲乙两人同时从跑道相向而行，经过6分钟相遇，两人据需走，4分钟后甲回到了起点，乙距离起点还有300米，求跑道全长。 A b two people at the same time from the runway at and do it, after six minutes, two people to meet according to walk, four minutes after the start point b a return to the starting point and 300 m distance, and the runway.The answer a total go 6 + 4 = 10 minutes, go all the way,So meet, b's journey is equivalent to a walk four minutes;So the speed and a second faster than is: soSet a 6 X speed is, the b speed is 4 X,For 10 minutes, there go just a whole journey, b and 300 m to go all the way,So there are:10 * 6 X = 10 * 4 X + 300Given the X = 15So a speed is 15 * 6 = 90 m/minSo the runway length is 10 * 90 = 900 m答案 甲一共走了6+4=10分钟，走完全程；所以相遇时，乙走的路程相当于甲走4分钟；所以乙的速度和甲的速度比是：6:4设甲速度是6X，则乙速度是4X，因为一共走了10分钟，甲刚好走完全程，乙还有300米走完全程；因此有：10*6X=10*4X+300解得 X=15所以甲速度是15*6=90米/分钟所以跑道全长是10*90=900米

1 Thank you for helping me with my math.2 He had never seen such a strange creature looking.3 She yelled at him and right up to tiddalik marches.4 Kangaroo did somersaults to make tiddalik laugh.5 You told i about the man he is.数学题1 答案是160页吗设总书页数为x，然后得方程式2/5*x+56=3/4*x 2 暂时没时间。。。不好意思

1.一次马拉松比赛，60名选手中的42名跑完了全程。有百分之几的选手没有跑完全程？解：（60-42）/60*100%=30%答：有30%的选手没有跑完全程 30% did not finish the marathon 2.两个连续正整数的乘积是132.他们的和是多少？解：设这两个连续正整数为x和x+1，由题意得： x（x+1）=132 由题意，解得：x=11则，这两个连续正整数为11和1211+12=23答：它们的和是23 Their sum is 23.
