Answer: each section is 56 meters long, accounting for 16% of the total length

Is one seventh of five meters one meter and five seventh of one meter () meters?

5/7

Five out of seven meters is one meter (), or one out of seven meters

Five out of seven
five

4.5X = 1.71

x=1.71/4.5
x=0.38

6X + 2 and 1 / 2 = 2.59 minus 4.5X = 4 and 1 / 2 and 1 / 4 (x + 0.25) = 45% 0.1 * 0.2 * 0.1 * 0.2 * x = 2
solve equations.
6X + 2 and 1 / 2 = 2.59 minus 4.5X = 4 and 1 / 2 minus 1 / 4 (x + 0.25) = 45% 0.1 * 0.2 * 0.1 * 0.2 * x = 2x divided by 40% * 2 = 2.25 14.5 minus 9.9 = 1.4x minus 9.42.2x + 2 and 4 / 5 4x = 12.53 * (0.4 + x) = 7.58x minus 1.8 = 10.8 divided by 2

5x-8=2y;2x+8=y
In this way, 5 (y-4) - 8 = 2Y, the result is x = 24; y = 56. But I can't get this result. I can get it by adding and subtracting elimination method and substituting elimination method 5x-8 = 2 (2x + 8). What's the problem

Your 5 (y-4) - 8 = 2Y is wrong. It should be 5 (Y-8) / 2-8 = 2Y [or 5 (Y / 2-4) - 8 = 2Y]. When you sort out 2x + 8 = y, it should be the original equation = > 2x = Y-8 = > x = (Y-8) / 2 = Y / 2-4, and then you can solve this equation system by substituting the algebraic formula of X into another equation

"You see, this math problem is very easy to check." how to change double negation

You see, is this math problem not easy to check

A math problem, help me check, is equal to 8
In this paper, we define some kind of operation "|", give two rational numbers a and B (a is not equal to 0), a | B = 2a-b, if | 1-x / 2 | [2 = 4, then the value of X is

Two solutions
X = 8 or - 4

Why is the calculation always wrong?
To build a road, the team built a quarter of its total length on the first day and the remaining three fifths on the second day, leaving 150 meters. How many meters is the total length of the road?
1000 is wrong!

150 / (1-1 / 4-1 / 4 * 3 / 5) = 500 (m)
