A fill in the blank question, please help solve it

If the ten digits are x, then the single digit is x+3

x+x+3=1/4(10*x+x+3)

2x+3=1/4(11x+3)

8x+12=11x+3

3x=9x=3

x+3=6, the original two-digit number is 36

Solution: If the single digit is x, then the ten digit is x+3

3x+x=[10(x+3）+x]*

4x=(11x+30)*

4x=11x*

4x=4x/4=

x=3x=3*

Suppose the ten digits are 3, then the single digit is 6, (3+6)=36*4 1

Let the ten digits be x and the single digit be y

y=x+3x+y=1/4(10x+y)

Solve the above equations.

x=3y=6

So this two-digit number is 36

Let's say the ten-digit number is x. Then the single digit is x+3;

Then this two-digit number is 10*x+(x+3).

According to the problem, there is (10*x+(x+3)) 4=x+(x+3), and x=3;

That is, this two-digit number is 36

A two-digit number, its single digit is 3 larger than the ten-digit number, and the sum of the single digit and the ten-digit number is equal to the 1 4 of this two-digit number, and this two-digit number is 32

o o /}

oo) ) You are.

A two-digit single digit and a ten-digit number are a and b, respectively, and the two-digit number falls to be exactly 5 times greater than 5 times the sum of its single digit and ten-digit number1

10b+a=5（a+b）+1

The solution is that since the single digit of 5 (a+b) = 0 or 5, then a = 1 or 6 if a = 1, then b = 1 If a = 6, then b = 5, then the original number is 11 or 56

Let the single digit be x and the ten digit number be x-3(x+x-3)*4=(x-3)*10+x

The length of the wire of the whole forest stove is: (the edge of the cuboid is long and resistant to the side) 6 + 4 + 2) 4 = 48cm

48cm is also the sum of the edge lengths of the cube, so the edge length of the square is:

48÷12=4cm

The volume and surface area of the cube are:

4×4×4=64cm³

4×4）×6=96cm²

According to the length, width and height of the cuboid, the total length of the iron wire can be calculated, and the length of the edge can be calculated according to the characteristics of the equal length of the cube side, and the formula of the nuclear area and volume can be quietly disturbed.

6。Explanation of the disadvantages: It can be known from the meaning of the title:

The length of this iron wire is: 4x(6+4+2)=48cm, so the edge length of the remade Zhengliang Zhonghua square iron frame is: 48 12=4cm, so the volume of this square iron frame is: 4 3=64cm 3.

The surface area of this cube iron frame is: 6x4 2 = 96 cm2.

The first one is 48, and the second one is (length, width and height) orange two.

Those who know each other and know themselves will not be defeated in a hundred battles; Knowing oneself without knowing the other, one wins and one loses; I don't know who I am, I don't know myself, I will lose every battle. ("Seeking Attack").

The word Kongming Three Kingdoms period military strategist statesman The two sentences of the Book of Commandments are from the "Book of Commandments" written by Zhuge Liang when he was 54 years old to his 8-year-old son Zhuge Zhan. But this is not Zhuge Liang's original. It is from the Western Han Dynasty's "Huainanzi Main Technique Training".

The original sentence is: "Therefore, there is no virtue without thinness, there is no far-reaching without tranquility, there is no both, there is no mercy without embracing the public, and there is no control without fairness and justice." ”

Sum 20, 19, 17, 14, (10) The blank space is 7

When the center is singular, the left side is different.

For example, 7-2=5, 7--2=5, 3--2=1 (1-1=0), fill in 7 centers as double, two on the right + lower left.

I tried one by one, but I found that it didn't work).

Answer: Bottom Left: 7Center: 0

In the system of equations, X is replaced by Y, Y is replaced by Z, Z is replaced by X, and the system of equations is unchanged, which means that x=y=z Replace the y on the right side of the equal sign with x in , and get the unary equation about x: 9x 2 (1+9x 2)=(3 2)x Solve this equation to get the double root: x=1 3 So the solution of the system of equations is x=y=z=1 3 Substituting the original system of equations to check and satisfy, so this is the solution of the original system of equations.
