: The opposite sides of a parallelogram are equal.
So, in above given figure
![3x+7=5x-17](https://tex.z-dn.net/?f=%203x%2B7%3D5x-17%20)
(measures of opposite sides)
![5x-3x= 17+7](https://tex.z-dn.net/?f=%205x-3x%3D%2017%2B7%20)
![2x= 24](https://tex.z-dn.net/?f=%202x%3D%2024%20)
![x= 24/2](https://tex.z-dn.net/?f=%20x%3D%2024%2F2%20)
![x= 12](https://tex.z-dn.net/?f=%20x%3D%2012%20)

If you would like to know how many pounds of pasta the restaurant will need, you can calculate this using the following steps:
3 pounds of pasta ... 14 people
x pounds of pasta = ? ... 56 people
3 * 56 = 14 * x /14
x = 3 * 56 / 14
x = 12 pounds of pasta
The correct result would be 12 pounds of pasta.
Answer:
35
Step-by-step explanation:
All angles of a triangle add up to 180 degrees, so you can add the other two angles, then subtract by 180.
This should be easy because we just have to use substitution method. Substitute the value of x from the second equation into the x of the first equation.
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15 ; y = 5
Substitute this value of y to either the first or second equation.
x = 2(5) = 10
The ordered pair is therefore (10,5).
