According to the calculations, the length of the enclosure is 100 meters, and the width is 50 meters.
To determine, using a linear system of inequalities, how long each side of the rectangle measures, the following calculation must be performed:
Length + width = Total fencing
- 125 x 2 + 125 = X
- 250 + 125 = X
- 375 = X
- 375 - 300 = 75
- 75/3 = 25
- 125 - 25 = 100
- 100 x 2 + 100 = X
- 200 + 100 = X
- 300 = X
- 200/2 = 100
- 100/2 = 50
Therefore, the length of the enclosure is 100 meters, and the width is 50 meters.

Answer: percentage of profit on the skirt is 11.1%
Step by step:
Let G denote price of gloves, and S the price of skirt, and let g dente the original cost of the gloves and s the cost of skirt. I will be using $ for the currency unit instead of the pound.
The sale equation is
$48 = G + S
100% profit on the gloves means:
G = 2 * g = 2 * $4
On the skirt, the profit is unknown ("x"):
S = x + s
We know that the total profit (total sale - total cost) after the sale is is 20%:
$48 - (s + $4) = 0.2 * (s + $4)
which finally gives us two equations with two unknowns:
$48 - (s + $4) = 0.2 * (s + $4)
$48 = 2 * $4 + x + s
which is straight-forward to solve. I got solutions as follows:
s = $36, x = $4
so the percentage of profit on the skirt is 100% * 4/36 = 11.1%

Answer:
x = -15/8
Step-by-step explanation:
-2(5x+8) = 14+6x
Expand the brackets.
-10x+-16 = 14+6x
-10x-16 = 14+6x
Add -6x and 16 on both dies.
-10x-6x = 14+16
-16x = 30
Divide -16 into both sides.
x = -30/16
x = -15/8
The solution for the equation is x = -15/8
