To create this inequality graph, you will have an open circle at 50 and an arrow pointing to the right.
Since the bag must be over 50, we draw an open circle at fifty.
Since the fee goes towards the bags over 50, we draw an arrow pointing to the right.
Answer:
The book costs $2 and the pencil also costs $2.
Step-by-step explanation:
It is easy to get the value of the book and the pencil if we use<em> algebraic expressions.</em>
Let x be the cost of the book and let y be the cost of the pencil.
The sum of 2 books and a pencil is $6.00
The difference of cost between 3 books and 2 pencils is $2.00.
Step 1: Let's get the value of y first.
2x + y = 6
y = 6 - 2x
Step 2: Let's substitute the value of y and look for the value of x.
3x - 2y = $2.00
3x - 2(6-2x) = 2
3x - 12 + 4x = 2
7x = 12 + 2
7x = 14
x = 
x = $2 (this is the cost of the book)
Step 3: Let's substitute the value of x and look for the value of y.
2x + y = 6
2 (2) + y = 6
4 + y = 6
y = 6 - 4
y = $2 (this is the cost of the pencil)
Let's check:
2x + y = $6
2(2) + 2 = 6
4 + 2 = 6
6 = 6<em> (CORRECT)</em>

Answer:
1. 9 * 5 in.
2. 3 * 15 in.
Step-by-step explanation:
Volume = 1/3 * area of the base * height
120 = 1/3 * A * 8
So A = 120 / (8/3)
= 120 * 3/8
= 45 in^2.
So the dimensions of the base could be 9 * 5 in
or 3 * 15 in.
