Answer:

D. 4

Step-by-step explanation:

∆VWZ ~ ∆VXY, therefore:

$\frac{VW}{VX} = \frac{VZ}{VY}$

VW = 8

VX = 8 + WX

VZ = 18

VY = 27

Plug in the values

$\frac{8}{8 + WX} = \frac{18}{27}$

Cross multiply

$8 * 27 = (8 + WX)*18$

$216 = 144 + 18WX$

Subtract 144 from each side

$72 = 18WX$

Divide both sides by 18

$4 = WX$

WX = 4

Solve the system of equations below.<br> x + y = 5<br> -4x – 2y = -8

mel-nik [20]

Answer:

x = -1 , y = 6

or (-1, 6)

Step-by-step explanation:

First solve for "y" in the second equation:

$-4x-2y=-8\\-4x+8=2y\\y=-2x+4$

and now, use this result as a substitution for "y" in terms of "x" in the first equation:

$x+y=5\\x+(-2x+4)=5\\x-2x+4=5\\-x=5-4\\-x=1\\x=-1$

Knowing the value of "x", now we place it in the substitution equation to find "y":

$y=-2x+4\\y=-2(-1)+4\\y=6\\$
