Teachers often all this problem a donut problem because it’s like the donut hole getting cut out of the middle. The way that you solve this is to find the area of the whole yard and subtract the area of the fountain. Since they are rectangles we’re going to use A = LW
Area of yard - Area of fountain
A = (8x)(9x) - (2x)(5x)
A = 72 x^2. - 10 x^2
A 62 x^2

K12? Me too.
It would be educated guess. I just finished that practice cause I'm catching up :) Good luck!
Answer:
The system of equations is
Step-by-step explanation:
Let
x ----> the number of minutes of calling time
y ----> the monthly cost of the calling plan
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
In this problem
Plan A
substitute
----> equation A
Plan B
substitute
----> equation B
therefore
The system of equations is
5/2 is a rational because this can be expressed as a ratio or fraction. 5/2 in ratio can be written as 2.5
