All, the words of the top students who know come in math thank you

2) The total tonnage of the cargo in the table has not changed.

3) The product of the tonnage transported per day and the number of days required is certain.

The reason: the number of days required has expanded, and the number of tons transported per day has decreased. The number of tonnes shipped per day has decreased, and the number of days required has increased.

Hope, thank you.

Kid, it's the second half of the sixth grade

1) Number of days needed: 3, 4, 5, 6

2) There is no change in the total amount or the ratio of the number of tons transported per day to the number of days required has not changed. (Recommended total amount).

3) There is an inverse proportional relationship between the number of tons transported per day and the number of days required: the more tons transported per day, the fewer days required; The fewer tonnes shipped per day, the more days are required.

Well, that's it, hope it helps you.

Happy learning! Hope!

1) **, fill in the following order: 3, 4, 5, 6;

2) The product of the tonnage of halo per day and the number of days required remains the same, that is, the total tonnage shipped out per day remains the same, which is 300;

3) inverse proportional relationship, the reciprocal of 300 150 = 2 = 1 2; 300 100 = 3 = the reciprocal of 1 3; 150 50 = the reciprocal of 2 6;

The number of tonnes transported per day decreased, and the number of days required increased in equal proportion.

2) The total number of goods in the table has not changed, it is all 300

3) The tonnage of daily shipments and the number of days required constitute a counterexample relationship, when the tonnage of daily transportation increases, the number of days required decreases, but their product, that is, the total number of goods, does not change.

The total number of shipments per day is constant.

The formula of the inverse proportional function is y=k x the number of days x the amount of transportation per day is y Bringing in the data in the table can be calculated k=300, that is, the product of the upper and lower data in the table is a fixed value of 300

3,4,5,6.Because substituting it into the inverse proportional function gives k = 300 and y = 300 x, and substituting it respectively gives us 3, 4, 5, and 6

(1) The unit price of 6:1 6 tennis balls is 6 yuan each.

3) 480:80=540:90 720:120=480:80If you feel that my answer is more satisfactory, I hope to give me an adoption! If you are not satisfied, you can continue to ask.

Pure hand begging to adopt thank you

Children, this kind of homework should be done by yourself, and you should think about it yourself.

Let the number A be x and the number B be y
