Answer:
The answer to the question provided is 60.
Answer:
Yes, her reasoning is correct
Step-by-step explanation:
Given the ratio: 109.2 : 6
Written in fractional form, we have:
![109.2: 6=\dfrac{109.2}{6}](https://tex.z-dn.net/?f=109.2%3A%206%3D%5Cdfrac%7B109.2%7D%7B6%7D)
Now:
Therefore, the student's reasoning is correct. In fact, as a check:
![\dfrac{109.2}{6}=18.2\\\\\dfrac{1092}{60}=18.2](https://tex.z-dn.net/?f=%5Cdfrac%7B109.2%7D%7B6%7D%3D18.2%5C%5C%5C%5C%5Cdfrac%7B1092%7D%7B60%7D%3D18.2)
We would obtain the same result in both cases.

The information about the coordinate plane shows that the slope of XV is 1.
<h3>How to illustrate the information?</h3>
From the information, the slopes of the diagonals are negative reciprocals. Therefore, the slope of UW is -1 and the slope of XV is 1.
The diagonals of kite UVWX are perpendicular.
It should be noted that negative reciprocals in a kite create a perpendicular bisector. So the two lines share a midpoint so they are perpendicular.

Answer:
x=3, y=-6
Step-by-step explanation:
As you know there are many ways to solve this question! First is Subsitutuion, Second is Elimination, and Third is Graphing!
Let’s begin with our detailed answer:
As you know subsitution is solving for a variable and then it can be used as a variable substitution to figure out x and y.
So in our system of equations:
![\left \ {3x+2y=-3}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B3x%2B2y%3D-3%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
I will just take one equation and solve for x but it actually dosent matter which variable you subsitutue and solve for.
![\left \ {3x+2y=-3}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B3x%2B2y%3D-3%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
To eliminate this question we can divide the top part by -3:
![\left \ {-9x-6y=9}} \atop {9x+4y=3}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%20%7B-9x-6y%3D9%7D%7D%20%5Catop%20%7B9x%2B4y%3D3%7D%7D%20%5Cright.)
Let‘s sum these system of equation and we get: ![y=-6](https://tex.z-dn.net/?f=y%3D-6)
We can now insert y as -6 and solve for x:
![3x-12=-3](https://tex.z-dn.net/?f=3x-12%3D-3)
![x=3](https://tex.z-dn.net/?f=x%3D3)
So, ![x=3, y = -6](https://tex.z-dn.net/?f=x%3D3%2C%20y%20%3D%20-6)
