3 9 = 27 should be the accommodation fee paid (25 yuan for the boss + 2 yuan rebate for the waiter).

And the extra 3 yuan is returned to the customer.

So the answer that started with the wrong (calculation: 3 9 = 27 is the result of the cost of accommodation is the wrong one) is incorrect.

This is a logical error.

I believe the questioner is a careless person.

Hehe (don't blame me, Pi Luchen).

You shouldn't have counted the two dollars that the waiter hid and argued nonsense, because those two dollars were also vacant by three people 30-3=27, 3x9=27, shouting 27=27!!

Question 10: If the speed of cycling is xkm hours, then the speed of the car is 2xkm hours.

20/x-20/2x=

10/x=x=20

Answer: Question 11: If x pieces are processed manually per hour, then the machine processes (2x+9) pieces per hour 4200x=3600x+1800 9

600x=1800×9

x=27A.

First of all, multiply the first fraction by 2 + root number 3 to get a fraction with a denominator of 1, which is 4 + 2 times the root number 3, and then subtract 2 times the root number 3, so the first part is only 4. In the latter part of the calculation, the -1 power is the meaning of the fraction, that is, the root number 3 + 1 part, this part can be multiplied by the root number 3-1 by the previous method, and then to the root number 3 of 2 minus 1 2. . . In the end, I got the answer 7 2-2 points of the root number 3

Treat root number 3 as a solution to it! Root number 12 is 2 root number 3
