Answer:
D) 180
Step-by-step explanation:
60/10 has no remainder, but 60/9 has a remainder, so it's not A
80/10 has no remainder, but 80/9 has a remainder, so it's not B
150/10 has no remainder, but 150/9 has a remainder, so it's not C
180/10 has no remainder and so does 180/9, so it's D
Answer:
![x=\frac{1}{2}\\\\y=-6](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B2%7D%5C%5C%5C%5Cy%3D-6)
Step-by-step explanation:
Given the following system of equations:
![\left \{ {{4x-11y=68} \atop {6x+5y=-27}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B4x-11y%3D68%7D%20%5Catop%20%7B6x%2B5y%3D-27%7D%7D%20%5Cright.)
In order to solve the system of equations using the Elimination Method, you can follow these steps:
- Multiply the first equation by -6 and the secondd equation by 4.
- Add both equations.
- Solve for "y".
Then:
![\left \{ {{-24x+66y=-408} \atop {24x+20y=-108}} \right\\.........................\\86y=300\\\\y=\frac{-516}{86}\\\\y=-6](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B-24x%2B66y%3D-408%7D%20%5Catop%20%7B24x%2B20y%3D-108%7D%7D%20%5Cright%5C%5C.........................%5C%5C86y%3D300%5C%5C%5C%5Cy%3D%5Cfrac%7B-516%7D%7B86%7D%5C%5C%5C%5Cy%3D-6)
- Substitute the value of "y" into one of the original equations and solve for "x":
![6x+5(-6)=-27\\\\6x=-27+30\\\\x=\frac{3}{6}\\\\x=\frac{1}{2}](https://tex.z-dn.net/?f=6x%2B5%28-6%29%3D-27%5C%5C%5C%5C6x%3D-27%2B30%5C%5C%5C%5Cx%3D%5Cfrac%7B3%7D%7B6%7D%5C%5C%5C%5Cx%3D%5Cfrac%7B1%7D%7B2%7D)
