Callia and Xuanxuan each have some cartoon stickers. If callia gives Xuanxuan 25 stickers, Xuanxuan's stickers will be three times as much as callia's. If Xuanxuan gives callia some stickers, callia's stickers will be six times as much as Xuanxuan's. how many stickers can Xuanxuan have at least?

Suppose that there are x stickers for callia, 3 (x-25) - 25 stickers for Xuanxuan, and 3 (x-25) - 25 = 3x-100 > x > = 34. Suppose Xuanxuan pastes the stickers for callia y, then the stickers for callia will be 6 times of Xuanxuan's. 6 (3x-100-y) = x + y18x-600-6y = x + y17x-600 = 7yy > = 1x > = 36. Take the integer 17x-600 = 7y17x-17 * 35-5 = 7 at the same time

There are more than 8 vehicles in 30% of the number of vehicles in the first team and the second team. If 24 vehicles are transferred from the second team to the first team, there will be the same number of vehicles in the two teams?

24 * 2 = 48 the second team is more than the first team
48+8=56
56/(1-30%)=80
80-48=32

First of all, we should understand the characteristics of numbers divisible by 17
If the difference is a multiple of 17, the original number can be divided by 17. If the number is still too large to be observed directly, repeat the process
Let this number be 5mn6, 5mn-30 divisible by 17, and this number be 5 (M-3) n, or 4 (M + 7) n. 47 + m-5n divisible by 17, that is (m, n) = (4,0), (9,1), (no, 2), (2,3), (7,4), (no, 5), (0,6), (5,7), (no, 8), (no, 9)
This number may be 506652365406557465916

If the side length of square ABCD is 4cm and the length DG of rectangular defg is 5cm, what is the width of rectangular defg?

Didn't you upload the picture? It's related to Pythagorean theorem. The width is 3

There are three cars, a, B and C, each driving at a certain speed from a to B. B starts 10 minutes later than C and catches up with C 40 minutes later; a starts 10 minutes later than B and catches up with C 60 minutes later. A catches up with B a few minutes later

A: B: C
B: C = 50:40 = 5:4
A: C = 80:60 = 8:6
Then a: B = 8 / 6:5 / 4 = 16:15
A is 15 times faster than B
A leaves 10 minutes later than B
10/(1/15)=150
A overtakes B 150 minutes after departure

In a test, there are 20 multiple-choice questions, 5 points for one question, 2 points for one wrong question, no answer, no score and no deduction. Xiaoming has 2 questions not answered, at least correctly______ The total score is no less than 60

Let Xiao Ming answer at least x questions correctly, then he answers 20-2-x questions wrongly. According to the meaning of the questions, we can get that: 5x-2 (20-2-x) ≥ 60, then we can get x ≥ 1357 ∵ x is a positive integer ∵ x = 14, that is, Xiao Ming answers at least 14 questions correctly

Trigonometric geometry consists of nine trigonometric geometry
Punctuation is added to form a mathematical problem, a good answer plus 100 points

Triangle, geometry, a total of nine. Triangle, a few

After the opening of the expressway, the distance of the long-distance bus from a to B has been reduced by 30 kilometers, while the average speed has increased by 30 kilometers per hour, which takes only 4 hours to reach?

The distance between a and B is x km, x4-x + 307 = 30x = 320, so the distance between a and B is 320 km

1、 A software company has developed a kind of library management software, and the initial investment in the development of advertising costs is 30000 yuan, and did not sell a set of software, the software company also has to pay 150 yuan for installation and debugging. If each set is priced at 400 yuan, how many sets of software should the software company sell at least to ensure that it does not lose money?
2、 We know that y = 3y1-2y2, where Y1 is positively proportional to x, Y2 is inversely proportional to X-2, where x = 1, y = - 1; X = 3, y = 13?
3、 The turnover of a cold drink shop in July is 1000 yuan. If the average growth rate of the monthly turnover in the third quarter is x, how many yuan is the total turnover of the cold drink shop in the third quarter expressed by the algebraic formula of X?

1、 X sets sold:
Profit = (400-150) x
Cost = 30000
No loss: profit > = cost
That is, (400-150) x > = 30000
x>=120
A: at least 120 units have been sold
2、 Let Y1 = ax, y2 = B / X
Substituting x = 1, y = - 1; X = 3, y = 13 into:
a=-1,b=39
So Y1 = - x, y2 = 39 / X
y=y1+y2=-x+39/x
3、 The monthly average is (1 + x) times that of the previous month
So the total turnover in the third quarter is 1000 (1 + x) ^ 3

1 / 2 + (2 / 3) + 4 / 5 + (1 / 2) + (1 / 3)
Write the calculation

I write directly about the process
-8+5+3+10-4-7-1+1.2+0.8-0.8+0.8-6+3.5+0.5+2-1-0.7-2.1
I'll wrap each group up for your convenience
（-8+5+3）+（10-4-7-1+1.2+0.8）+（-0.8+0.8）+（-6+3.5+0.5+2）-1-0.7-2.1-0.5
In fact, it is to add or subtract some of the numbers that can be rounded up or offset
The final answer is - 1-0.7-2.1-0.5 = - 4.3
