Answer:
Option B) (-1,7,5) is correct.
The solution to the given system of equation is (-1,7,5)
Step-by-step explanation:
Given system of equations are



To find the solution of the given system of equations by using Elimination method:
Now adding equations (1) and (2)


_________________

________________


(since "-" getting cancelled)
Now adding equations (1) and (3)


_________________

________________



Now adding equations (4) and (5)

Therefore y=7
Substituting y=7 in equation (4)




Therefore x=-1
Now substituting the values x=-1 and y=7 in equation (1) we get




Therefore z=5
Therefore the solution to the given system of equation is (-1,7,5)
Therefore Option B) (-1,7,5) is correct.

Answer:
19.1
Step-by-step explanation:
Let's assign some variables to this triangle.
angle A = 63°
angle B = unknown
angle C = 71°
side a = 18
side b = y
side c = x
By the law of sins, applicable to ALL triangles, we have:

Let's then take the equation for angles A and C, in order to isolate the c (which is our x to find).
we then have

So, the answer is the second one.
The problem is asking what unit rate is the graph showing
If you would like to know how much in total employee benefits does Marisol receive, you can calculate this using the following steps:
14.5% of $50,000 = 14.5% * 50,000 = 14.5/100 * 50,000 = $7,250
The correct result would be c. $7,250.
