Here is your answer
B. (12,30)
REASON:
Given,
.......(i)
.......(ii)
Putting the value of y from eq.i in eq.ii we get
![3x-(2x+6)=6](https://tex.z-dn.net/?f=3x-%282x%2B6%29%3D6)
![3x-2x-6=6](https://tex.z-dn.net/?f=3x-2x-6%3D6)
![=6+6](https://tex.z-dn.net/?f=%3D6%2B6)
![x=12](https://tex.z-dn.net/?f=x%3D12)
Putting x=12 in eq.i we get
![y= 2x+6](https://tex.z-dn.net/?f=y%3D%202x%2B6)
![y= 24+6](https://tex.z-dn.net/?f=%20y%3D%2024%2B6%20)
![y= 30](https://tex.z-dn.net/?f=%20y%3D%2030%20)
So,
![\bold{x=12 and y= 30}](https://tex.z-dn.net/?f=%5Cbold%7Bx%3D12%20and%20y%3D%2030%7D)
Hence answer is (12,30) in which x=12 and y=30

Answer:
6 vans
Step-by-step explanation:
If 1 van can seal 18 students...
116 ÷ 18 = 6.4
Since it's not a whole number, we will estimate it to the nearest whole number which is 6.

Answer:
cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...
