Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)
k/5.2+81.9 = 47.2 // - 47.2
k/5.2-47.2+81.9 = 0
0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2
0.19230769*k = -(81.9-47.2) // : 0.19230769
k = (-(81.9-47.2))/0.19230769
k = 5.20000006*(47.2-81.9)
k = 5.20000006*(47.2-81.9)

Answer: the option A.
The elimination method consist is adding the two equations in a way that one variable be eliminated..
In order to do that you might have to manipulate on of the equations prior to add the two equations.
In this case, ff you multiply the second equation by - 1 you will get
- x - y = - 4
which you can add to the first equation
2x + y = 8 to eliminate the y.
Answer:
16.25=1.75x
Step-by-step explanation:
so write it like this to that the bigger number(16.25) is on the left then write the other number(1.75)then put the X by the 1.75

Answer:
125°
Step-by-step explanation:
The angles in a qadrilateral always adds up to 360° so to get the fourth angle, you add the angles given and subtract it from 360°
72°+98°+65°+x = 360°
235°+ x = 360°
x = 360°-235°
x = 125°
