Answer:
In algebra, the inequality will refer to a number, or range of numbers, which are either greater than, greater than or equal to, less than, or less than or equal to a fixed value. This can be shown on a number line using lines and circles. The line indicates the range of possible values. The circle is the end point of the line.

Step-by-step explanation:
Additive identity is a property that involves the sum of two or more integers in an equation without compromising the equality of the equation.
Given the equation
(5+2)+n = 7+n
We can see that the right hand side of the equation is derived from the left hand had by addition of the values in parenthesis.
Given the right hand side;
= 5+2+n
= (5+2)+n
adding the expression in parenthesis will give;
= 7 + n
Since we added the expression in parenthesis to arrive at the expression at the right hand side, hence additive identity was used in the calculation.
Bill and Joe have 60 dollars between them. Bill has half as much as Joe.
so Bill = B and Joe = J
20 (B) + 40 (J) = 60
Bill has half the amount of Joe, and so 40/2 = 20
subtract 60 from 20 (the answer for Bill) and you get 40, (the answer for Joe)
