First of all we will eliminate x from our equations. In order to do that we will use our first and second equation and then we will use second and third equation.
Upon subtracting 2 equation from 1 we will get,
Now we will use second and third equation to eliminate x.
Adding 2nd and 3rd equation we will get,
Now we will find out y from our 4th and 5th equation.
Upon subtracting 5th equation from 4th equation we will get,
Now let us find out z by substituting y's value in 5th equation.
Now we will find x from by substituting y and z's value in equation 1.
Therefore, x=1, y=1 and z=0 is the solution of the given system.

Answer:
5π/6 radians
Step-by-step explanation:
The whole is the sum of the parts.
∠BAD = ∠BAC +∠CAD
∠BAD = π/3 + π/2 = π(2/6 + 3/6)
∠BAD = 5π/6
Answer:
not a function
Step-by-step explanation:
We can use the vertical line test to tell if this is a function
If a vertical line touches the graph at more than one point it is not a function
Since this graph is a vertical line, it will fail the vertical line test.
Therefore, this is not a function
Answer:
True
Step-by-step explanation:
We have seen this take place numerous times throughout history. the value of a countries currency goes down and so does the hole economy. we can see this even happen in Germany after WWII and in multiple other places so yes the answer is true.
Answer:
33.3%
Step-by-step explanation:
If all of them are equal out of 100%
that means Roses are 33.3 daffodils are 33.3 and lilly's are 33.3
