|X-1 | + | X-10 | denotes the distance from X to 1 + the distance from X to 10 on the number axis. Obviously, the minimum value is 9, so long as X is between 1 and 10. Similarly, the minimum value of | X-2 | + | X-9 | is 7, when x is between 2 and 9. The minimum value of | x-3 | + | X-8 | is 5, when x is between 3 and 8. The minimum value of | x-4 | + | X-7 | is 3

When a takes different values, the root of the equation 3x + a = X-7 with respect to X is less than - 3

3x+a=x-7
2x=-a-7
x=-(a+7)/2
x-1

If 1 / 2 * 3 = 1 / 2 x 2 / 3 x 3 / 4, 1 / 7 * 4 = 1 / 7 x 2 / 8 x 3 / 9 x 4 / 10, what is the value of 1 / 2 * 4 + 1 / 3 * 3?

1/2*4 + 1/3*3
=1/2×2/3×3/4×4/5+1/3×2/4×3/5
=1/5+1/10
=3/10

Find the value of X: 8:3: x = 5:0.6,6:1 X: 4:3 = 7:1,5:2
4 and 2:1 and 7:2 = 1 and 3:1: (4-x)

3 and 13 / 21

What is the value of X
The values of are equal

1/3x+1=2/3x-7/3
x+3=2x-7
3+7=2x-x
x=10

X-1 / 3 x = 7 / 12

x－1／3x=7／122／3x=7／12 x=7／12?? x=7／8

In X of 7, when x = (), its value is 3?

In 7 x, when x = (21), its value is 3

1. Solve the equation x △ 1.32 = 0.5 1 / 3 + 1 / 4 = 7 / 30
X △ 1.32 = 0.5 1 / 3 + 1 / 4 = 7 / 30

1、
x/1.32=0.5
x=1.32*0.5
x=0.66
two
x/3+x/4=7/30
4x/12+3x/12=7/30
7x/12=7/30
x=12/30
x=0.4

When X-Y = 7, xy = 3. Find the value of X + y

Square, and then can be substituted

x/3=y/2 10%x-7%y=1%
Solve the following equations
x/3=y/2
10%x-7%y=1%

From 1 we get x = 1.5y ③
Substituting into equation 2, we get
0.1×1.5y-0.07y=0.01
0.08y=0.01
y=1/8
In equation 3
x=3/16
So:
x=...
y=.
