Come on, math problems!! Quick, a math problem!!!!

kilogram) kilogram).

Large: kg) Small: kg).

Big: Small:

What's that, don't fight with me on the first floor, you have so many points, what about mine??? Few and far between...

Set a large bottle of oil x kilograms.

2×3/4x=(

x=Big:Small: No matter how little I have, I'm not less.

Solution: Set up x kg of oil in large bottles and y kg of oil in small bottles.

x+y=x-1/4x ：y+1/4x=3 ：2

x=y=A: It turns out that the large bottle of oil is filled with kilograms, and the small bottle of oil is filled with kilograms.

Kilograms for large bottles, kilograms for small bottles. I don't even have to argue about teaching math.

If there are x kilograms for large bottles, then kilograms for small bottles.

Therefore (x-x 4) :( x 4+:2

Then the solution is x=

So the big bottle has kilograms, and the small bottle has kilograms.

1.Health index: MH2

2.Xiao Ming's Health Index:

45 Xiao Ming is unhealthy and thin.

1)m/h^2

2) 45 Xiao Ming is unhealthy and thin.

1、m/h^2

Xiao Ming's physical condition is unhealthy and thin.

Let the two largest and smallest numbers be removed, and the remaining x number will remain.

then the sum of these numbers = 10 (x + 2).

By removing the largest one, the remaining arithmetic mean is 9, resulting in a maximum number + 9 (x + 1) = 10 (x + 2) and a maximum number = x + 11

By removing the smallest one, the remaining arithmetic mean is 11, resulting in a minimum number + 11 (x + 1) = 10 (x + 2) and a minimum number = 9 - x

Obviously, when the minimum number = 0, x is the largest, x = 9, and this number is the largest, with x + 2 = 11.

Maximum = 9 + 11 = 20

A: There are up to 11 of these numbers. The largest of these numbers has a maximum value of 20.

What is the arithmetic mean?

There are x numbers, the maximum is A, and the minimum is B

9*(x-1)+a=10*x=11*(x-1)+b gives a-9=x, 11-b=x

So 20=a+b

The maximum is 20, a total of 11.
