Answer:When you know two of the dimensions and either the volume or surface area, you can find the third dimension. Find the width of a rectangular prism using the formulas for volume and surface area, which are volume = length x height x width, and surface area = 2 x length + 2 x height + 2 x width.

Hi there!
First, let's find the slope of the two points using the slope formula (y2 - y1 / x2 - x1).
S = 4 - 2 / 3 - 5
S = 2 / -2
S = -1
Next, we'll plug in the slope and a point into point-slope form (y - y1 = s(x - x1)) in order to find an equation. I will show the work using both points, which will result in two different equations.
(2,5)
y - 5 = -1(x - 2)
y - 5 = -x + 2
y = -x + 7
(4,3)
y - 3 = -1(x - 4)
y - 3 = -x + 4
y = -x + 7
The two equations came out the same! Which is completely okay, and happens sometimes.
Hope this helps!! :)

Answer:
Unitary cost per card= $0.21
Step-by-step explanation:
Giving the following information:
Number of cards per packecge= 25
Total cost per package= $5.25
<u>To calculate the unitary cost of each card, we need to use the following formula:</u>
Unitary cost per card= total cost / number of cards per package
Unitary cost per card= 5.25 / 25
Unitary cost per card= $0.21
