The equation is (0.75)9 + c = 20.
<h2>Linear system</h2>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
<h3>Simplification</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
Jimmy is selling used books at a yard sale.
A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill.
<h3>To find </h3>
The equation.
<h3>How to find the equation?</h3>
A customer buys 9 books at a cost of $0.75 each and pays with a $20.00 bill.
Let c be the profit.
Profit = Selling price - cost price
c = 20 - (0.75)9
On simplifying, we get
(0.75)9 + c = 20
So the equation is (0.75)9 + c = 20.

Answer:
8 slices
Step-by-step explanation:
To answer this question, we first need to know the area covered by the pizza.
Since it is circular in shape, we use the formula for the area of a circle.
Mathematically area of a circle = pi * r^2
Here, we were given the diameter but we know that D = 2r or r = D/2. This shows that the radius would be 14/2 = 7 inches
Now the area of the pizza is 22/7 * 7 * 7 = 22 * 7 = 154 square inch
Now we proceed to calculate the amount in calories present in the pizza;
That would be 154 * 14.04 = 2162.16 calories
one slice has 270 calories; The number of slices in 2162.16 calories would be 2162.16/270 = 8.008 which is approximately 8 slices
<span>9.095 divided by 0.17 is 53.50
</span>
Y=9.25 because inorder to solve this we need to first take 5*.3 which equals 1.5 now that we have this we can move on we now have the equation 1.5 + 2y = 20 so now we need to continue working on getting y by it self so we subtract 1.5 from each side and then that leaves us with 2y=18.5 now we divide by 2 which leaves us with y=9.25
