Answer:
The correct option is 1.
Step-by-step explanation:
Inconsistent system: If the given system has no solutions, then it is an inconsistent system.
Consistent and independent system: If the given system has only one solutions, then it is an consistent and independent system.
Consistent and dependent system: If the given system has many solutions, then it is an consistent and dependent system.
The given equations are
.... (1)
..... (2)
Add both equations.



Substitute this value in equation (1).



The system of equations has only one solution, i.e.,(3,5).
Therefore the given system is consistent and independent. Option 1 is correct.

Step-by-step explanation:
Answer: Amber use 30 feet of basic tiles and 6 feet of decorative tiles.
Step-by-step explanation:
Let x be the foot of basic tiles and y be the foot of decorative tiles.
Now, according to the question, we have the following equations
![x+y=36\\y=36-x\ .......(1)\\\\8x+20y=36\times10\\2x+5y=90.......(2)\ \ \ [\text{divide equation by 4}]](https://tex.z-dn.net/?f=x%2By%3D36%5C%5Cy%3D36-x%5C%20.......%281%29%5C%5C%5C%5C8x%2B20y%3D36%5Ctimes10%5C%5C2x%2B5y%3D90.......%282%29%5C%20%5C%20%5C%20%5B%5Ctext%7Bdivide%20equation%20by%204%7D%5D)
Put y=36-x in (2), we get

Hence, Amber use 30 feet of basic tiles and 6 feet of decorative tiles.
