$\bf \begin{array}{llll}
-5x-y=5\\
-5x+y=5\\
-------\\
-10x+0=10
\end{array}\implies -10x=10\implies x=-1$

so if x = -1, let's plug that in the second equation

-5(-1)+y = 5
5+y = 5
y = 0

Solve the equation v^3=80

Luba_88 [7]

Answer:

4.31

Step-by-step explanation:

Find the cube root of both sides of the equation.

$^3\sqrt{v^3}$ = $^3\sqrt{80}$

The cube root will cancel out the cubed in the variable.

v = $^3\sqrt{80}$

Find the cube root of 80. I rounded to the nearest hundredth.

v = 4.31
