Cut a 5-meter rope into 11 sections, two of which are 10 / 11 meters long To say the result, and explain the reason. Understand must help me

correct
5 m 11 segments, so each segment is 5 / 11 M
So the second section is 2 * 5 / 11 = 10 / 11 meters

Cut a 7 meter long rope into 5 sections, each section is () meters

Cut a 7-meter-long rope into 5 sections, each section takes up (1 / 5) of the rope, and each section is (7 / 5 or 1.4) meters

Cut the 5-meter-long rope into 6 sections. How much is each one meter

Cut the 5-meter-long rope into 6 sections,
So each segment is 5 / 6 meters
It's 5 / 6 of a meter

Solve the equation: 48 + 5x = 63 think of 5x as a ()

48 + 5x = 63 think of 5x as an addend

6 (5x + 10) = 3600

6（5X+10）=3600
5X+10=3600÷6
5X=600-10
5X=590
X=590÷5
X=118

6.5x-x=10.

6.5x－x=10.5
5.5x=10.5
x=1.90909...

Solve the equation x + 1.5x = 10

I don't think this number is auspicious
Let me tell you
x+1.5x=10
2.5x=10
x=4

1.5x + 2 × 1.3 = 10.1
The binding group had to bind 1468 exercise books, each 20 of which was packed in a box. After that, there were still 8 copies left. How many boxes were there?
Two questions

1.5x=10.1-2.6
x=7.5/1.5
x=5
Set up x boxes
20x+8=1468
x=73

-(- 5x) - (+ 7x) = (- 4) ^ 2 this is an equation

-（-5x）-(+7x)=(-4)^2
5x-7x=16
-2x=16
x=-8

The solution of (7x-650): (5x + 650) = 3:4, part by part!

(7x-650):(5x+650)=3:4
4(7x-650)=3(5x+650)
28x-2600=15x+1950
28x-15x=2600+1950
13x=1550
x=350
