Let's say there are a total of x balls in the bag.

The starting red ball accounts for 1 4, then the starting red ball has 1 4*x.

And then I put 10 more, so now there are 1 4*x+10.

At this time accounted for 2 3 of the total

So we can get the equation: 1 4*x+10=2 3*x and get x=24Answer: There are 24 balls in the bag.

Let there be x red balls at the beginning.

4x+10=(x+10)*(3/2）

x=2, so there are balls in the bag, 4x=8 (pcs).

2x+4)*3=2*5x

6x+12=10x

x=3 The first question says that there are 24, and the meaning of the two x's before and after you is different.

6 red + 10 red = 16.

24 + 10 = 34.

34=16*？？You didn't go to elementary school.

10 (2 3-1 4) = 24.

There are 24 balls in the bag.

One: Suppose there are x balls.

x/4+10=2x/3

3x+120=8x

5x=120

x=24two:(2x+4):5x=2:3

2x+4)/5x=2/3

Multiply 15x on both sides

6x+12=10x

4x=12x=3

Your equation is closed with x=3.

I don't know if you are asking the question above about the number of red balls or the total number of balls.

10 paper clips connected with 9 junction points, (4 cm + 6 mm) *5 + 4 cm - 6 mm * 3) * 4 + 4 mm - 6 mm.

23 cm + cm + cm.

Centimeter.

I won't understand that I can draw.

Which question? Is it "de-entry computing"? If yes:

Original = 500 - 25 15

Original = -

Original = 36 [(5 6) 3 - 2 3) 3] = 36 (5 2 - 2).

How do you do this physics problem? The process is artificial rainfall, and the artificial rainfall bomb with a mass of m=4kg should be launched straight up to an altitude of 4500 meters on the ground, and the rain booster should be sprinkled when the rainfall bomb reaches the highest point. The air resistance is negligible (g takes 10m s).

Find: (1) the instantaneous kinetic energy of the artificial rainfall bomb off the ground (2) how long it takes for the artificial rainfall bomb to rise to the highest point.

It's simple.

1: Original = 1 2-1 3 = 1 6

2: Original = 1 2-1 3+1 3-1 4+1 4-1 5....1/2017-1/2018+1/2018-1/2019=1/2-1/2019=2017/4038
