Answer:
0.1875
Step-by-step explanation:
You can't. There are an infinite number of different parallelograms,
with different dimensions, that all have area of 96 square miles.
Knowing the area doesn't tell you the dimensions.
Here are a few parallelograms with areas of 96 square miles:
-- square, every side 4√6 miles long
-- rectangle, 12 miles long, 8 miles wide
-- parallelogram, base=32 miles, height=3 miles
There are an infinite number of others.
The equation is provided below:
x = cost of DVD player
3x = cost of the movies
$532 = total amount purchased for the DVD player and the movies
$532 = x + 3x
$532 = 4x
$532 / 4 = 4x / 4
$133 = x (cost of the DVD player)
$133 * 3 = $399 (cost of the movies)
To check if the equation is correct:
$532 = $133 + ( 3 * $133)
$532 = $133 + $399
$532 = $532
The correct answer for the cost of the movies will be $399.
