"<em>A number, y, is equal to the difference of a larger number and 3.</em>"

<u>You can rearrange this equation to find the matching answer choice:</u>

"<em>The same number is one third of the sum of the larger number and 9.</em>"

<u>You can rearrange this equation to find the matching answer choice:</u>

Option B is correct.
Step-by-step explanation:
We need to identify which of the following equations has exactly one solution.
We will solve each equation to find the answer
A. 
Solving and finding value of x:

This equation has infinite number of solutions because both sides are equal to 0
B. 
Solving and finding value of x:

This equation has exactly one solution
C. 

This equation has no solution because both sides are not equal.
So, Option B is correct.

Answer:
Step-by-step explanation:
(A)
A=hw, h=1.5w
A=1.5w^2
(B)
A=(h+8)(w+8), h=1.5w
A=(1.5w+8)(w+8)
A=1.5w^2+12w+8w+64
A=1.5w^2+20w+64
The independent variable is the # of hrs.
the dependent variable is # of gallons.
the slope is -125.
the y intercept is 13000

To approximate the number of chairs that can be set up in floor space, we just have to divide the total floor area by the area that each chair needs. That is,
n = (40 ft x 32 ft) / (4 ft x 5 ft)
n = 64
Therefore, there are 64 chairs that can be set up in the floor.
