You have made the fractions clear first! If you want to put brackets, you can't understand what you wrote!

Halo two or three questions are not clear "" The number after the " " is in parentheses.

Hope it helps, thank you.

1.The ratio of trees planted this year is (2) :(1), and this ratio is (2).

2.The ratio of distance to time is (600) :(5) and the ratio is (120km h), which indicates the speed of the train.

3.The ratio of the circumference to the diameter is (d) :(d), and the ratio is ( ) This ratio represents (pi).

Combined with the above, you can check pi!

First of all, we need to understand the meaning of root addition, which is the value of the unknown number x that you have calculated, so that the value of the simplest common denominator 2 (x-2) is 0

Here's how to do it: The first step is to find the value of x.

Multiply the two sides of the equation by 2(x-2) to get: 2(2-k)=3(x-2) solves: x=10-2k 3

Step 2: Substituting x=10-2k 3 into the simple common denominator 2 (x-2), when its value is 0 to get (10-2k) 3-2=0

The solution yields k=2

So when k=2, the fractional equation 2-k about x, x-2=3, 2 has an increasing root.

2-k/x-2=3/2

x=5-3/2k=2

k=21-k/x(x+1)+3=0

Q2 1-k=0, k=1 Root increase may be 0 and -1

1.Simplified: x=(10 3)-(2 3)kBecause the original equation has an additional root, x=2

10/3 - 2/3 k = 2

The solution yields k=2

square meters).

5dm = 50cm, to build a square wooden frame because there are 12 pieces of wood, and there is only one 50cm piece of wood, so the length of each piece is 50 12=, and the area of the paste paper = square centimeters.

The volume of the frame = cubic centimeters.

Sum of cube edge lengths = 12 edges = 5 decimeters.

Edge length = 5 12 dm.

The area of the paste paper = 6 square of the edge length = 6 5 12 5 12 = 25 24 square decimeters.

The volume of this frame = the cube of the edge length = (5 12) 3 = 125 1728 cubic decimeters.

1. Edge length = 5 12

2. The area of the paste paper = (5 12) square.

3. The volume of the frame = (5 12) cubes.

The side length of the frame is 5 12 decimeters.

The surface area of the frame, i.e. the area of the paste, is 6 5 12 5 12 = 25 24 square decimeters.

The volume of the frame is the cubic of the side lengths.

a=2,b=1

The process is as follows: in the equation of the line at the substitution point (1,4) 4=k+k so k=2 the linear equation is y=2x+2

Therefore, the intersection with the x-axis and y-axis is respectively at the point a(-1,0)b(0,2)ab= 5 ab slope is 2 because pq ab so pq slope is -1 2, pq=ab= 5 columns can be obtained.

b-0) (0-a)=-1 2 a*a+b*b=5a=2b 5b*b=5 b=1 (because a,b is greater than 0 so there is only one solution) a=2b=2 b=1

From the meaning of the title, we can know that 4=k+k---k=2

So the function is y=2x+2

So we know a(-1,0),b(0,2),ab= 5Because p(a,0),q(0,b), so pq= (a +b) because pq=ab, so there is a +b =5

Then by pq ab, so the slope of the straight line pq is k=-1 2, so a=2b

So 5b = 5, b = 1, b = 1

So a=2, b=1

Solution: The function y=kx+k passes through the point (1,4), and brings in k=2. Therefore, the function equation is y=2x+2, and a(-1,0),b(0,2) can be obtained. AB = 5

From pq ab, the pq equation for the straight line can be y=-1 2x+b, (if the two straight lines are perpendicular, then the product of the slope of the two straight lines can be obtained as -1, and the x-axis y-axis is a special case) thus a=2b.

and pq=ab, get a + b =ab = 5, that is, 5b = 5, b = 1 or -1 by the title, b 0, so b = 1, a = 2b = 2. i.e. a=2, b=1 (draw the picture first, easy to understand).

Substituting the point (the primary function y=kx+k is y=2x+2, the coordinates of point A are (-1,0), and b is (0,2).

pq=ab i.e.

The square of a + the square of b = 5

Because of pq ab, the slope k of the straight line pq is -1 2, and the two straight lines are perpendicular, and the slopes are negative reciprocal to each other.

i.e. b (-a) = -1 2 and a = 2b

b=1,a=2 (a,b>0)
