Answer:
Step-by-step explanation:
Answer:
Allie got $120, Barbara got $240 and Carson got $80.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
Allie got x.
Barbara got y.
Carson got z.
Divide $440 among themselves
This means that ![x + y + z = 440](https://tex.z-dn.net/?f=x%20%2B%20y%20%2B%20z%20%3D%20440)
Barbara gets 2 times as much as allie.
This means that ![y = 2x](https://tex.z-dn.net/?f=y%20%3D%202x)
Carson gets 1/3 as much as barbara.
This means that ![z = \frac{y}{3} = \frac{2x}{3}](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7By%7D%7B3%7D%20%3D%20%5Cfrac%7B2x%7D%7B3%7D)
Finding x:
Replacing in the first equation.
![x + y + z = 440](https://tex.z-dn.net/?f=x%20%2B%20y%20%2B%20z%20%3D%20440)
![x + 2x + \frac{2x}{3} = 440](https://tex.z-dn.net/?f=x%20%2B%202x%20%2B%20%5Cfrac%7B2x%7D%7B3%7D%20%3D%20440)
Multiplying everything by 3
![3x + 6x + 2x = 1320](https://tex.z-dn.net/?f=3x%20%2B%206x%20%2B%202x%20%3D%201320)
![11x = 1320](https://tex.z-dn.net/?f=11x%20%3D%201320)
![x = \frac{1320}{11}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1320%7D%7B11%7D)
![x = 120](https://tex.z-dn.net/?f=x%20%3D%20120)
Finding y and z:
![y = 2x = 2(120) = 240](https://tex.z-dn.net/?f=y%20%3D%202x%20%3D%202%28120%29%20%3D%20240)
![z = \frac{y}{3} = \frac{240}{3} = 80](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7By%7D%7B3%7D%20%3D%20%5Cfrac%7B240%7D%7B3%7D%20%3D%2080)
Allie got $120, Barbara got $240 and Carson got $80.
Hi!

![Answer---->=-137](https://tex.z-dn.net/?f=Answer----%3E%3D-137)
Explanation: <u><em>This question is super super easy to me. This question is about how to use their order of operations the math problems. First you had to used PEMDAS stands for P-Parenthesis first, E-Exponents second, M-Multiply third, D-Divide fourth, A-Add fifth, and S-Subtract sixth. Then multiply and divide from left to right with 6*7=42. Then 27*9=243,42-243+64, and add or subtract from left to right with 42-243+64=-137 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>
Hello,
The answer is x= y-13 / 2 ( everything after the x= is a fraction)
How to solve;
Start by subtracting 13 from both sides of y=2x+13, we do this to get the x on 1 side
So now we have y-13=2x
Next divide both sides by 2, we do this to get x by it self.
y-13/2=x
Now we flip the problem and there you have it!
Edit: The x does not have a Pos or neg value, The only way to know what x is, is to solve for x.
