First, multiply the first equation by 3 to get:
![3x+3y=-6](https://tex.z-dn.net/?f=3x%2B3y%3D-6)
Then, add the two equations together to get
![8x=16](https://tex.z-dn.net/?f=8x%3D16)
We can follow that x=2. Plugging in x=2, we get that y=-4.
Therefore, the solution of (2,-4)

Step-by-step explanation:
Please have a look at the photo attached in this answer
The missing part of the angle is 32 degrees, so the total angle of B is:
32 + 73 = 105 degrees.
Let x is the distance from airport A to airport C to the nearest tenth of a mile, we use cosine law to find x:
=
- 2(570)(390)cos(105)
<=>
= 592070
<=> x =
= 769.46 miles
Answer: 40%
Step-by-step explanation:
They won 10 out of 25, so we can write it as a fraction:
