A super easy elementary school math problem 5

Analysis: A total of 14 + 11 = 25 boxes were packed in two times.

The first time I received a plastic bag of 25 * 7 12 = 14 + 7 12 boxes, so 7 12 boxes are 35 plastic bags.

1 box is 35*12 7=60 plastic bags.

There are 60*25=1500 plastic bags.

The general formula of the column is:

35 [(14+11)*(7 12)-14]*(14+11)=1500 (only).

A: There are 1500 plastic bags in total.

If each box should be filled with x plastic bags, then.

14x+11x)*7/12=14x+35

Solution x=60

So there are a total of (14x+11x)=25x=1500 plastic bags.

First there are x plastic bags, and then there are columns:

14x+11x)*7/12=14x+35

Solution x=60

So there are a total of (14x+11x)=25x=1500 plastic bags.

A: There are 1500 plastic bags in total.

35 [7 12-14 (14+11)]=1500 (pcs).

A: There are 1500 plastic bags in total.

Take three of the four cards 0, 1, 3, and 5 and form a three-digit number as required. (Write at least 2 of each).

Odd number: 103,301,135,153......Even numbers: 310, 350, 130, 530 ......

Odd multiples of 5: 105,135,315,305 ......An even multiple of 3: 150,510, which is a multiple of 2 and a multiple of 5: 130,310,150,510,350,530 ......

Odd number: 103 105 135 301 305 Even: 130 150 310 Odd multiples of 5105:

An even multiple of 105 135 315 3053: 150 510

It is both a multiple of 2 and a multiple of 5: 130 150 310 350 510 530

Odd : 501,503

Even numbers: 130, 150

Odd multiples of 5: 105,305

Even multiples of 3: 150,510

That is, a multiple of 2 and a multiple of 5: 310,350

Did you write o or 0? If it's o, there won't be, and if it's 0, there will be 24!!

To put it simply: there are 20 multiples of 5s in 1 100, where 25 contains 2 5s, 50 contains 2 5s, 75 contains 2 5s, and 100 contains 2 5s, in fact, there are 24 5s, and each 5 can get a 0, so there are 24 zeros

336 42% = 800 This is the total number of students.

800-336=464 This is the number of walking students.

1-42% = 58% This is the rate of students who walk.

Total population: 336 42% = 800 (people).

Walking: 800-336=464 (people).

Percentage of total population: 1-42%=58%.

Solution: Total number of people = 336 42% = 800 (people).

So the number of people in the cloth = 800-336 = 464 (people).

Proportion = 100% - 42% = 58%.

Walking percentage: 100%-42%=58%.

336 42% = total population.

Total number of people - 336 = number of people walking.

The ratio is: 100-42=58

The number of people is: 336 total people), 800-336 = 464 (number of people walking).

There were 464 people walking, accounting for 58%, and the total number of primary school students was 800.

You're giving this picture quite big, I can't see it clearly, I'm helpless.

Can you tell me about the title, the picture can be seen clearly, when the title is really not clear.

2x=12+6

Solution: 2x=18

x=9 I wish you progress in your studies! If you still have questions, please ask me. If you have any other questions, please help me.

Find the volume of the large cube first: 20 20 20 = 8000 cubic millimeters.

Find the volume of the cuboid: 6 6 20 = 720 cubic millimeters.

The volume of a small cube: 6 6 6 = 216 cubic millimeters.

Because there are 3 such boxes, but the small cubes are repeated 2 times.

So the volume of this part: 8000 720 3 216 2 = 6272 cubic millimeters.

Didn't you say it's super easy? So why not do it yourself?

This.. You didn't say how to pierce it, whether the three sets of holes can intersect or what.
