Give the correct answers to the following questions and answer the following questions

It's all found in it, so don't ask questions like that.

2+2+2=6

3x3-3=6

3 8 + 3 8 + 3 8 = 6 (where 3 8 is called the third root of 8).

2+2+2=6

3 (4+4)+4=6 is the cube root of 4+4+4+65 5+5=6

8-4 (8+8)=6 is the fourth root of 8+8 minus 8 = 6 9 9- 9 = 6

The first question is that 2 + 2 + two equals six. The second question. 3 Chen San. Minus three.

Seven up and eight down, three long and two short, living and dying together, insignificant, falling out of the water, in danger, half pushing and half doing.

Staggering, methodical, subdued, frustrated, able to bend and stretch, push through the old and bring forth the new, sacrifice oneself for others, look left and right, and suffer for oneself.

From beginning to end, good and bad, happy and evil, joyful, scrambling to be the first, horizontal and vertical.

Speak in unison, duplicitous, learn from each other's strengths, return to the same end in different ways, suitable for all ages, happy and sad.

Question 4: Ingenuity, helplessness, listlessness, can't help it, elated, countless, a thousand shots, concentrated.

Immersive, express their opinions, be domineering, be the same on the outside and on the inside, rejuvenate the country and the country, be approachable, die as they deserve, and bear the guilt of pleading.

Returning to Zhao after the end, the magic plan rises from the ground, works together, the fog fills the sky, the wind roars, and no effort is spared.

The morning and evening are beautiful, criss-crossed, smiling, self-made, gold-picking, choppy and meticulous.

Candle night tour, ignore it, hold your head high, Ruixue is a good year.

Half-believed, staggering, subdued, able to bend and stretch, push through the old and bring forth the new, sacrifice oneself for others, look left and right, say the east and the west, go in the opposite direction, rush to the first, cross the line, speak in unison, duplicity, learn from each other's strengths, and make up for each other's weaknesses, suitable for all ages, happy and sad.

Lu Zhishen broke the cauldron and sank the boat, and Zhao Kuangyin was impressed.

Lu Zhishen Lu Meng --- Wuxia Ameng, impressive.

Xiang Yu --- embattled and shipwrecked.

Zhuge Liang --- seven captures and seven verticals, the grass boat version borrowed arrows, bowed to death and then died, and the light power Bo Mingzhi Meng Weijun - the rooster cries and the dog thief, and the cunning rabbit three holes.

Solution: Original, if a<0then a >0....True inverse, if a >0, then a <0

If a>=0, then a <=0

False inverse no, if a <=0, then a>=0 false.

7 Set the original length of the spring x

The coefficient of elasticity k (which is the equation k you listed).

So the analogy equation 2=k(

The solution is k=2 x=

So the spring is taken from the original length.

8 .According to the title, there can only be three coins for one yuan (six or five, obviously impossible, if it is four, then there are a total of 11 for five cents and one cent, but if this is the case, the number of five cents and one cent is a decimal, impossible, and the same is true for two and one, so there are only three).

Then set x for one cent, and y for five cents.

A system of column equations. The solution is x=5y=7 three of one yuan, seven of five cents, and five of one cent.

9 From A to B is uphill, and the downhill road is cleverly shot and collapsed x,y

x He Tachibana 3+ (

y/3+(y=x+3/10

The solution yields x=y=3

Answer: It is uphill from A to B, and the downhill distance is 3km

10 solution: It took 10 hours for Xiaoyuan in the upstream A to drive at a constant speed to the downstream B.

The available equation is s=(v+3)*10

It took less than 12 hours to return from B to A at a constant speed.

Equation s (v-3)*12 is obtained

Synaccio v 3 or v 33

11 Suppose the number of rabbits bought by the two people a year ago is x, then a year later, the number of rabbits raised by Lao Zhang is x+2, and the number of rabbits raised by Lao Li is 2x-1.

Because Lao Zhang's number of rabbits does not exceed two-thirds of Lao Li's rabbits.

The column equation is: x+2 2 3x(2x-1).

De: x 8 means that Lao Zhang bought at least eight rabbits a year ago.

12 There are 109 groups in total, with the largest group being 109,110,111

Solution: Let three continuous positive integers be (x-1), x, (x+1), then from the known, the equation is obtained:

x-1）+x+（x+1）<333

x<111

2 x 110,110-2+1=109, so the sum of three consecutive positive integers in the 109 group is less than 333, and the largest group is 109,110,111

Your sister has so many questions, and you have to count so much, just 20 points, and I'm not interested in doing the third question.
