Urgent question 01010017 and 01010025 two quotas can be applied at the same time in a project, pleas

The efficiency ratio of A and B is two-fifths: three-fifths, which is 2:3, and the time ratio is their inverse ratio, which is 3:2

To do it separately for x days list the ratio 3:2=15:x x=10

10 times 36 equals 360.

Solution: Set up passenger cars to travel x kilometers per hour.

x-5/7x=5

2/7x=5x=

English isn't it, I'm sorry for you.

Well, I understand what you said, what are you asking?

There are three digits in mouth 4, which is divided by 8, and the quotient obtained has 0 in the middle and no remainder, indicating that the quotient is a three-digit number, so the highest digit in the dividend can only be 8 (if it is 9, the middle digit of the quotient is not 0).

After determining that the highest digit of the dividend is 8, then the middle digit must be less than 8 (because the middle digit of the quotient is 0).

Note that there is no remainder, so the middle digit of the dividend can be either 2 or 6.

It can be seen that there are two possibilities for the dividend, which may be 824 and 864 respectively.

I don't know what you mean, big brother, I'll talk about it in detail.

Is the second push of your first question bx? You check that the question is correct and correct, and then give you the answer.

After bringing up the copy item box, click on the first bai in the above picture to a red circle, and then go to select the name column of your figure du2, click import after completion, and then click to view the custom sequence, where the new name sequence appears.

Then select the data area in Figure 1, sort, click the option in the figure below, select the new name sequence that has been generated in the custom sort order, and select the keyword to your corresponding column to get Figure 3.

If the name is not repeated, use the vlookup formula for serial number, age, and class.

Yes, you can set the order in Figure 2 to a custom sequence, and Figure 1 can be sorted by name.

I usually solve this sort problem by using a custom function.

Use the vlookup formula, =vlookup(

Find values, data ranges, column ordinals, 0), such as you.

In Table 2, Wang Huadong's age is the public power formula of the version of the cell is =vlookup(b2,"Table 1! b1:d6",2,0）。Don't copy this formula directly, let you understand it.

First initials? Something that isn't logical doesn't seem to be sorted automatically.

Equipment income = 30*

B equipment income = 40*

So it is advantageous to buy B equipment.

Scheme A; 30*

Option B; 40*

Option B is advantageous.
