Sixth grade math problems, I m going to hand them in tomorrow soon

36x2 9=8 (pcs).

8 (1-80%)=40 (pcs).

40-8=36 (pcs).

A: 8 for basketball and 36 for football.

6 3 55 = 110 (pages).

110x6 11=60 (pages).

A: Read another 60 pages to finish the book.

Solution: 7+2=9

36x7 9=28 (pcs).

36x2 9=8 (pcs).

I bought x more of them.

80%(36+x)=28+xx=4

6 (5 11-1 5-1 5) = 6x55 3110 (pages).

110x1 5=22 (pages).

22 + 6 = 28 (pages).

110-22-28=60 (pages).

Soccer 8 4 = 32 Basketball 32 80% (1-80%) = 8.

2 .Solution: There are x pages in this book.

1/5x+6+1/5x):x-

Set x for football and y for basketball.

x+y=36

x:y=7:2

7y=2x2x+2y=72

y=8x=28

There are x soccer balls in the setting.

80:20=z:8

z=32 now 32 in football and 8 in basketball.

The book has x pages.

x=5:11

5x=66+

x=110110=11x

11/6=11/x

x=60 There are still 60 pages left to finish the book.

36-28=8 basketball.

40-8 = 32 footballs.

2.Solution: The book has 5x pages.

2x+6）：（3x-6）=5:6

132*6 5+6=72 pages.

1.The volume ratio of salt to water in bottle A is 4:3, and if there is 200 ml of salt water in bottle A, the salt is 200*4 7

The volume ratio of salt to water in bottle B is 3:1, and if there is 300 ml of salt water in bottle B, the salt is 300*3 4

It's strange to look at this number, is it inscribed incorrectly)

2.The two cars are traveling in the opposite direction, so the total speed is the sum of the two cars, which is 96km h for five-sixths of an hour, and the distance is 96*5 6=80 (km) The distance between the two cars is still one-fifth of the whole journey, then the distance = 80 (1-1 5) = 100 (km).

3.The ratio of boys to girls is 2:3, i.e. the number of boys is two-fifths of the total class size, and because there are 12 fewer boys than three-fifths of the total class size.

12 people are one-fifth of the class size.

Then the class is 12 (1 5) = 60 people.

60 * 2 5 = 24 boys, 60 * 3 5 = 36 girls.

The volume ratio of salt to water is 4:3 The volume ratio of salt to water is 3:1

Is this still called salt water?

1. Solution: Let these books be discounted before x yuan, and the equation can be obtained:

x=28 bought a book for yuan, and it turned out to be 28 yuan.

2. The solution is large: set the original price of x yuan, the first house to buy the money is: 24 * the second house to buy 21 units, send 4 units, the actual money spent is: 21x so the first house socks are cost-effective.

3. Troublesome Ant Vertical Solution: If the cost is X yuan, the usual price is Yuan, and the price of June Day:

x = 150 costs 150 yuan.

I rub the current elementary school students are really awesome and don't help themselves do the math.

The area of the large circle minus the area of the small circle.

Xiao Ming is not right, because the original weight is equal, but cup A is divided into 1 + 2 3 parts, and cup B is divided into 1 + 3 4 parts, and the amount of each part is different and cannot be added. The correct ratio should be 7:17.

In this way, each cup is a multiple of the common, and each serving is the same and can be added.

Let the weight of the juice in the two cups of A and B be x

The weight of the juice powder in cup A is 1 3x, and the weight of water is 2 3x; The weight of the juice powder in a cup is 1 4x, and the weight of water is 3 4x

If you pour them all into a cup of C, then the weight of the powder juice in the cup C = 1 3x + 1 4x = 7 12x, and the weight of water = 2 3x + 3 4x = 17 12x

At this time, the weight ratio of fruit juice powder to water in cup C is 7 12x:17 12x=7:17

There must be a mistake in the question you asked, and according to the text of the question you entered, I feel that there is no solution.

Now I pour them all into a cup of C, and the weight of the juice and water in the cup is 1:3Now I pour them all into the C cup, so what is the weight ratio of the juice powder to the water in the C cup at this point? "There must be something wrong with this text.

Thinking for yourself, relying on others is not enough.
