This is a linear equation y = mx, where:
m= slope or reading rate:
x = the number of minutes
y = the number of pages read.
So the equation becomes: y = 4.5.x
How many minutes it will take to read 90 pages (y):
90 = 4.5.x or x = 90/4.5 and x = 20 minutes
So the ordered pair will be (20,90)

Step-by-step explanation:
Answer:
Step-by-step explanation:
If the books length (L) is three times as long as the width (W), the equation for area is this:
L · W = 20 inches,
3W · W = 20 inches - substituting L for 3W
So then the books perimeter is
