Answer:
$3.00
Step-by-step explanation:
Let p = the cost of a pack of pencils
and b = the cost of a binder
Then we have two simultaneous equations.
(1) 2p + 3b = 21.00
(2) 5p + 2b = 25.00
1. Multiply each equation by numbers to give one of the variables the same coefficient.
Multiply (1) by 2 and (2) by 3.This gives
(3) 4p + 6b = 42.00
(4) 15p + 6b = 75.00
2. Subtract (3) from (4)
This gives
(5) 11p = 33.00
3. Solve equation (5) for p
Divide each side by 11
p = 3.00
Each pack of pencils costs $3.00.
The expression that represents the volume of the rectangular prism, in terms of the width w, is given as follows:
6w³ cubic units.
<h3>How to obtain the volume of a rectangular prism?</h3>
A rectangular prism is composed by three dimensions, given as follows:
The volume of the rectangular prism is given by the multiplication of these three dimensions, as follows:
V = lwh.
From the image given at the end of the answer, the dimensions of the prism are given as follows:
Hence the expression that gives the volume of the rectangular prism is given as follows:
V = w x 2w x 3w = 6w³ cubic units.
