Answer:
In a square, all sides are equal. This means that each side is 3x inches in length.
The sum of the sides is 48 inches
There are 4 sides in a square.
3x + 3x + 3x + 3x = 48
<em>12x = 48</em> ----> is the equation
This means that x = 4
Each side is 3x inches in length, hence each side is also 3(4) which is 12 inches or 1 feet.

Answer:
The number is 20.
Step-by-step explanation:
To solve this, first take the words and turn into an equation.

3/5x + 8 = x
8 = 2/5x
20 = x
