Answer:
Step-by-step explanation:
Divide both sides by 4:
f 5 + x = 12, and you add -5 to the left side of equation, what should you add to right side of equation?

Hi there! :)
<u><em>Answer:</em></u>
<em><u>x=7</u></em>
<em><u>*The answer must have a positive sign.*</u></em>
Step-by-step explanation:
<h2><u><em>Lesson: Addition/Subtraction/Multiplication/and Division property of equality</em></u></h2>First, you switch sides of an equation.
Then, you subtract by 5 from both sides of an equation.
You subtract by the numbers from left to right.
<u><em>Final answer is x=7</em></u>
I hope this helps you!
Have a nice day! :)

Given:
Carrie has 180 ft of the fencing and wishes the fence to be 4times as long as it is wide.
To Find:
The area in square feet that the fencing encloses.
Answer:
The fence encloses 3600 sq ft.
Step-by-step explanation:
Let x denote the length of the dog run and y denote the width of the dog run.
Given that the garage wall serves as one side of the dog run, we are left with 3 other sides to instal the fence.
Carrie has 180ft of fencing with her, so the sum of the lengths of the 3 sides has to be equal to 180. We can represent this in the form of an equation as
We are also given that Carrie wishes the fence to be 4 times as long as it is wide.
So,
Replacing this value into the first equation, we have
Therefore,
Thus, the length of the dog run is 120ft and the width is 30ft.
The area enclosed will be equal to the length multiplied with the width. So,
The fence encloses 3600 sq ft.
When you see questions of this nature, test the individual inequalities and look out for their intersection.
For
Choose a point in the lower or upper half plane created by the line
The above line is the one which goes through the origin.
Now testing (1,0) yields,
That is,
This statement is true. So we shade the lower half of
For
We test for the origin because, it is not passing through the origin.
This yields
This statement is false so we shade the upper half.
The intersection is the region shaded in B. The top right graph
