In fact, this problem belongs to the chemistry section. Recall that many other sciences require mathematical calculations. The problem will belong to Mathematics only if no knowledge of other sciences are required to solve the problem.
Solubility for the given substances is measured in grams per 100 g of water at a particular temperature (20 deg.C).
This means that the mass (assumed to be the solute) will not change the solubility, just the minimum quantity of solvent (water) will.
Thus the solubility of sodium chloride will remain L=36 g/100g H2O for any quantity of solute. Similarly, the solubility of lead nitrate will remain as K=54 g/100 g H2O.
The reason that they remain constant is because the quantity of solvent (water) is fixed at 100 g. Varying amount of solute will affect the quantity of solvent required, but not the solubility.
I'll leave it to you to calculate the difference between K & L.

Answer:
y = -6x — 13
Step-by-step explanation:
use y = mx + b equation and plug in what you know.
5 = -6(-3) + b —> solve for b
b = -13 —> plug in what you know into y=mx+b
ANSWER: y = -6x — 13
Answer: Domain of function is 
or (0, 
)
Step-by-step explanation:
Assuming x as width of rectangle
so, Width = x
Question says, Length is 5in more than 3 times id width.
we write as Length = 3x+5
Therefore, Area of rectangle will be given function f(x)
f(x) = x(3x+5)
Here, It is important to notice that width and length of rectangle will always be positive values and also, area of rectangle is always positive.
we can write in equation as
Thus, Domain of function is or (0, )
The GCF of 18 and 72 would be the first step.
the gcf is 18
So we we now have 18 (x^2y)(xy)
factor both variables
18xy would be the gcf
