1. If Xiaoyi has sugar x, then Xiaohong has sugar x+13, Xiaoliang has sugar 2x+26, and the total number of sugar cubes.

4x+39<=50, get x can take 0,1,2. The total number of sugars obtained was 39, 43, 47

4+7=11, so the total number of sugars is 47, Xiaoyi 2 pieces, Xiaohong 15, Xiaoliang 30. There are also 2+1+5+3+0=11.

The other two cases are not on topic.

2. There are X yachts, Y students, ten people per boat, and the last boat is left with Z people, then 1<=Z<=9, there is.

6x+18=y

10（x-1）+z=y

1<=z<=9

The solution obtains that x=7-z 4, and the problem x, y, and z are all integers, so z is a multiple of 4, and 1<=z<=9, so z can take 4 or 8, and the result is.

a. There are 6 boats left, with a total of 54 people.

b. There are 5 boats left, with a total of 48 people.

There are two solutions to the second question, what is the grade of this question, and it is not a math planning question, nor is it an inequality question that I like to take in high school, but it involves inequality and planning. Fainted, who fooled such a simple topic.

Xiaohong should be 1 more than Xiaoyi, right? Assuming that Xiaohong is x block, then Xiaoyi is x-1, Xiaoliang gets 2x blocks, so x+x-1+2x=11, the answer is Xiaohong 3 blocks, Xiaoyi 2 blocks, Xiaoliang 6 blocks

First estimate the number of ships, I estimate that there are 5 ships, then the number of people is 48 people, to meet the first situation, when each ship has 10 people, it also needs 5 searches, and the last one is not full. The second scenario is met, so there are 5 ships and 48 people

Hello, hydrostatic velocity = (10+6) 2=8 km/h.

In fact, the three people who stayed only spent a total of 27 yuan, and the 27 yuan included 2 yuan for the waiter's private swallowing of the late potato and 25 yuan for the boss, and the remaining three yuan were returned. The total of 27 yuan spent by the three of them included 2 yuan for the waiter, so the 2 yuan and the total cost of the handstool could not be added. Therefore, the conclusion is:

In fact, it didn't cost 30 yuan, each person paid 9 yuan, a total of only 27 yuan, the code hunger boss got 25 yuan, the waiter took 2 yuan, there is no less than 1 yuan.
