It s no point, just ask a question, and the masters will help

What kind of square are you talking about, concrete, steel? Or something?

If it's just a quadrilateral pit, I have a solution, which is to use 10 to dig out a ramp on one side of the quad, then lay the sticks on the ramp into a railroad-like track, and finally tie the stone slab with a rope, push the slate down on the track, six people pull it in front, four people push it back, and it is very easy to get outside.

If it's concrete or steel, I haven't thought of it yet, so let's think about it together.

What is a quadrangular body? Big pit? If it's a dirt pit, as it says when you fall on it, dig a chute and spread a stick on the ground, and then pull it up with a rope, and if it's concrete or steel, there's only one way to get it out (concrete with a breaker, steel with gas or waterjet), otherwise there's no other way

I didn't have that dollar in the first place.

Nine pieces for each of the three people is 27 pieces.

The boss took 25

There are also 2 pieces that were taken off by the waiter.

It doesn't match numbers like 29 or 30.

This question itself is misleading everyone, in fact, 27 yuan = 25 yuan + 2 yuan hidden by the waiter, and the remaining three yuan was returned to the three people.

There is this 1 yuan, but because 25 is divided by 3, it is equivalent to each person only paying more than 8 yuan, so this topic is a bit confusing.

2/3*2/5=4/15

A: The area of the lawn is 4 15

3/5×2/3=2/5

The lawn area occupies 5 points of the campus area2

1. It may indeed cause trouble, and lessons should be learned, but the problem is not too big, so you should not be in a hurry.

2. If the car has a traffic accident, it may involve your aunt, if the other party tells the truth, the person who bought the car is responsible, and it has nothing to do with your aunt. Now I am afraid that there will be a big accident, the car will be destroyed and people will die, and people will not understand the situation, so they will chase the owner of the car to your aunt.

3. The current method: one is to find the car buyer and ask for the brand certificate back; Second, if you don't give it, you can also handle the transfer; The third is to file with the license plate issuer, explain the situation to them, and solicit opinions to see how to deal with it.

It's all junior high school, right? Basically, the equation is solved, and the eighth question sets the original price of clothes to be x yuan? The original price x = yuan that discount ( 6% off Other principles are similar.

1Are all RT triangles, ABC and RT triangles, ACDs similar? (How similar triangles prove, I forgot.) ）

If so, the answer is easy to explain.

The square of AC + the square of BC is equal to 169

AC+BC) squared = AC squared + BC squared + 2*AC*BCAC BC= under the root number (169+2*AC*BC) in a similar triangle column 6 than BC=AC ratio 13AC*BC=78

ac bc = under the root number (169 + 2 * 78) = 325 under the root number, this question is a bit bad to put under this category, right?

x=y+480

x=3y, why is it incomplete...? Do you think the question is not rigorous.........
