Answer:
see the procedure
Step-by-step explanation:
Identify
Let
x ---> the cost of the Xbox one at Walmart
Strategy
we know that
The cost of the Xbox one at Walmart multiplied by 2 plus $50 must be equal to $450
Set up
The algebraic expression that represent this situation is
![450=2x+50](https://tex.z-dn.net/?f=450%3D2x%2B50)
Solve
solve for x
![450=2x+50](https://tex.z-dn.net/?f=450%3D2x%2B50)
![2x=450-50\\2x=400\\x=\$200](https://tex.z-dn.net/?f=2x%3D450-50%5C%5C2x%3D400%5C%5Cx%3D%5C%24200)
Check
substitute the value of x in the equation
![450=2(200)+50](https://tex.z-dn.net/?f=450%3D2%28200%29%2B50)
----> is ok
Answer:
The solution is
.
Step-by-step explanation:
Given:
The inequality given is:
![|x|+4>7](https://tex.z-dn.net/?f=%7Cx%7C%2B4%3E7)
In order to simplify for 'x', we first isolate 'x' on one side.
Adding -4 on both sides, we get:
![|x|+4-4>7-4\\\\|x|>3](https://tex.z-dn.net/?f=%7Cx%7C%2B4-4%3E7-4%5C%5C%5C%5C%7Cx%7C%3E3)
Now,
is an absolute value function which is defined as:
![|x|=\left \{ {{-x}\ \ x](https://tex.z-dn.net/?f=%7Cx%7C%3D%5Cleft%20%5C%7B%20%7B%7B-x%7D%5C%20%5C%20x%3C0%20%5Catop%20%7Bx%5C%20%5C%20x%5Cgeq0%7D%7D%20%5Cright.)
Therefore, the given inequality can be rewritten as:
and ![x > 3](https://tex.z-dn.net/?f=x%20%3E%203)
Therefore, the solution is
.

I JUST TOOK THE QUIZ
Answer:
4.5
Step-by-step explanation:
First we need to turn the ratio of 1 : 3 into a fraction
1:3 = 1/3
Next we need to square that fraction
1 x 1 = 1
3 x 3 = 9
Then we turn those numbers into a fraction
1/9
We turn the .5 into a fraction
.5/x
And cross multiply both fraction by each other
1/9 x .5/x
1 x X = X
9 x .5 = 4.5
So
4.5 = X
