Both of these variables represent a common measure used in chemistry.
The amount of material/volume is the material’s concentration.
The rate is the reaction is increase by altering the concentration.
-5y-6y is -11y=-22 so y=2
Since the two lines are parallel then they have the same slope which = 1/3
since the line passes through (-6 , -8)
y+8 = (1/3)(x+6)
3y + 24 = x + 6
x - 3y = 18 is the equation

Given:
Perimeter = 18 m
The formula for the perimeter of a rectangle is:

Where:
l = lenght
w = width
In this case, we have that:
l = 2w
Therefore, we substitute the values in the formula:

And solve for w:

For the length:

Answer:
The width is 3 m
The length is 6 m
