Circle + Circle + Circle + Triangle + Triangle =

Circle + Circle + Triangle + Triangle + Triangle =

2) Subtract (1) formula to get:

Triangle - Circle =

Triangle - Circle =

Circle + Circle + Circle + Triangle + Triangle =

Round + Round + Round + Round + Round +

Round + Round + Round + Round + Round +

Circle = Triangle = Circle +

Circle + Circle + Circle + Triangle + Triangle =

Circle + Circle + Triangle + Triangle + Triangle =

Subtracting the above formula from the following formula yields:

Triangle - Circle =

From the above formula plus the following formula, we get:

5*(Circle + Triangle) = 4

Solve the circle = triangle =

2.Circle + Circle + Circle + Triangle + Triangle =

Circle + Circle + Triangle + Triangle + Triangle =

Add the left side of the equation to have circle + circle + circle + triangle + triangle + circle + circle + triangle + triangle + triangle =

i.e. 5 circles + 5 triangles = 4, so 1 circle + 1 triangle = 4 divided by 5 = in the formula circle + circle + circle + triangle + triangle = , it becomes 2 circles + 2 triangles + 1 circle = so there are 2 * circles = so circles =

Triangle =

1、===

2. It is easier to understand that this should be done with primary school thinking.

The first equation is multiplied by 2 and the second equation is subtracted by 3, leaving a triangle = then a circle =

1 question ===

Question 2: Treat the circle as x and the triangle as y

3x+2y=

2x+3y=

Solve the equation to obtain: x=y=

So circle = triangle =

1.= Garden + 5 Triangle = 4 Garden + Triangle =

Triangle - Garden = 2 Triangle = 1

Triangle = Garden =

684 minus 52 times 6, then divide by 8, and you're OK.

The answer is meta.

Let a football be a dollar x and a basketball (x+7) and establish the equation: 8x+5(7+x)=360 to solve x=25 so a football is 25 yuan a piece and a basketball is 32 yuan a piece.

It's very simple, you first calculate the money used to buy football, and the rest is the money to buy basketball, you divide the total price of basketball by the number of basketballs, which is the unit price of basketballs. (684-6×52）÷8

The money used to buy football: 52 6 = 312 yuan.

The money used to buy a basketball: 684-312 = 372 yuan.

Number of basketballs: 372 8=.

That's a bad question.

One: 3840 6 = 640 (pcs).

640 10 = 64 (pcs).

10 + 10 = 20 (sets).

64 20 = 1280 (pcs).

1280 6=7680 (pcs) Answer: .

2: (1) 66666 10001 + 66666 6666 = 66666 (10000 + 1) + (33333 2) (2222 3).

3. Let the largest number be x, then the other 4 numbers are x-1, x-2, x-3, and x-4 respectively

x+(x-1)+(x-2)+(x-3)+(x-4)=1980

5x-10=1980

x=398 A: The largest number is 398

Four: (1) 1+2-3-4+5+6-7-8+9+10-......1990

1. How many days did a scientific expedition team spend on March 1 this year when they set off to investigate a certain place and returned on August 4?

31 + 30 + 31 + 30 + 31 + 4 = 157 days.

2. A kindergarten has 18 classes and has received a total of 720 donated books, how many books can each class get on average?

720 18 = 40 volumes.

3. A bag of infant milk powder is 123 yuan, and a bag of middle-aged and elderly milk powder is 45 yuan, how much does it cost to buy 5 bags of these two types of milk powder?

840 yuan.

Now 260 12 (12+1) = 240 tons per month.

So water saving 260-240 = 20 tons.

, 260 minus 260 multiplied by 12 divided by 13 equals 20 tons, saving 20 tons per month.

b=4 c= **。

4.(1) Solution: Let the boy have x people according to the meaning of the topic:

The solution is x=70

2) Solution: Let the length be x and the width be y, then there is: x+y=15, y=2x

x=5,y=10 So the area s=xy=503) solution: let x tons per hour unload has: 12x + solution x=4) solution:

Let Xiaoqing be x years old: 9x-8x=4 so x=45) solution: let 2 points have x pieces, then 5 points are (27-x) pieces.

The solution gives x=15, which is 15 pieces of 2 points and 12 pieces of 5 points.

1 24x2-2x15=18

2 can be calculated with the formula in which a= b=4 c=

3 Weigh 20 grams out of 9 and 11, then 3 grams out of those 20 grams, and take out the 3 grams and you're left with 17 grams.

4 。1 male 70 (74+10) divided.

2 Set length x, width y, (x+y)x2=30, x=2y, length 10 width 5 area = xy=10x5=50

3 Set unloading x tons per hour 12x+ ,x=

4 Let the father be x years old, the mother be y years old, and the little green z years old x=9z , y=8z, x-y=4 ; x=36, y=32z=4 Xiaoqing is 4 years old, father 36, mother 32

5 5x + 2x (27-x) = 90 (90 is a dollar = 90 cents) after making x (5 cents) = 12 coins, 2 cents = 27-12 = 15 coins.

x （2 ）—2 ）x 15 = 18

2、a= b=4 c=

9-3 (i.e. 11 grams and 9 grams and weights on one side of the scale, and 3 grams of weights and ** on the other side of the scale).

1。There are 70 boys.

2。The area of this rectangle is 50 square centimeters.

3。Set to unload x tons per hour, then there is.

12x= x=t).

4。Xiaoqing is 4 years old, his father is 36 years old, and his mother is 32 years old.

5。Xiao Ming has 15 coins for 2 cents and 12 coins for 5 cents.

1) 3 (2) a= b=4 c= (3) put 9 grams and 11 grams on one side and 3 grams and 17 grams on the other side** 11 + 9 = 3 + 17

4) <1> set the number of male students as x x = 70 < 2> set the length x as the width as y x=2y 2x + 2y = 30 x = 10 y = 5 the area as xy = 50 square centimeters "3" set the unloading per hour x 8-12x= x= x=

4> Let Xiaoqing's age be x 9x-8x=4 x=4 <5> 5x+2*(27-x)=90 x=12 out of 5 and 15 out of 2.

2、a= b=4 c=

3.Put ** and 3 grams of weights on one side, 9 grams and 11 grams of weights on the other.

4.（1） -10=74 x=70

2) Let the width be x, then the length is 2x, 6x=30 x=5 So, the area = 5*10=50

3) Unloading x tons per hour, 8=12x+ x=

4）9x-8x=4 x=4

5)x+y=27

x= 15 y=12
