We are given with the formula
p = 200k - 500
a) The constraint for this formula is obtained from the idea that the profit must be positive
200k - 500 > 0
k > 500/200
k > 2.5
b) To make 14000 profit
14000 = 200k - 500
k = 72.5 or 73 knives must be sold
The age of the Harry in the terms of variable <em>x, </em>as the age of his father is (x+4) is represent with following equation.

How to write algebraic expression? </h3>
Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
Harry is one third as old as his father and his father is x+12 years old.To find the age of Harry, we need to convert the given statement into the algebraic expression.
Suppose the age of the Harry is <em>a</em> years and the age of his father is<em> b</em> years. Now Harry is one third as old as his father, thus

Let the above equation is equation one.
As the father of Harry is x+12 years old. Thus put the value of age of his father in the equation one as,

The age of the Harry in the terms of variable <em>x, </em>as the age of his father is (x+4) is represent with following equation.

Answer:
yes
Step-by-step explanation:
because we are simply "adding" 2 negative numbers.
-8n + -7 = -7 + -8n
as long as we flip the terms around with their signs, the commutative principle of addition applies.
what we CANNOT do is e.g.
8n - 7 = 7 - 8n
THERE would be a problem.
but again, by also keeping the signs with the terms, it is all OK.
so, yes, we could also do
8n - 7 = -7 + 8n
that is true again.
