Answer:
x=11, y=8/3
Step-by-step explanation:
Consider quadrilateral LMNO. If this quadrilateral MUST BE a parallelogram, then
LM=NO
and
LO=MN
Thus,
![\left\{\begin{array}{l}4x+4=5x-7\\ \\x-7=3y-4\end{array}\right.](https://tex.z-dn.net/?f=%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bl%7D4x%2B4%3D5x-7%5C%5C%20%5C%5Cx-7%3D3y-4%5Cend%7Barray%7D%5Cright.)
Solve this system of two equations. From the first equation:
![4x-5x=-7-4\\ \\-x=-11\\ \\x=11](https://tex.z-dn.net/?f=4x-5x%3D-7-4%5C%5C%20%5C%5C-x%3D-11%5C%5C%20%5C%5Cx%3D11)
Substitute it into the second equation:
![11-7=3y-4\\ \\3y-4=4\\ \\3y=4+4\\ \\3y=8\\ \\y=\dfrac{8}{3}](https://tex.z-dn.net/?f=11-7%3D3y-4%5C%5C%20%5C%5C3y-4%3D4%5C%5C%20%5C%5C3y%3D4%2B4%5C%5C%20%5C%5C3y%3D8%5C%5C%20%5C%5Cy%3D%5Cdfrac%7B8%7D%7B3%7D)
THE HALF OF 3/4 WOULD BE 0.375
Answer:
The answer is B.
Step-by-step explanation:
9 : 12 = 3 : 4
12 : 16 = 3 : 4
