I need to know how to solve this anyone?

I can't make out what the radius of the sphere is, but the equation you're looking for is:

$V=\frac{4}{3}\pi r^3$

For example:

If the radius of a sphere is 5 m, it's volume would be,

$V=\frac{4}{3}\pi (5)^3$

$V=\frac{4}{3} (3.14)(5)^3$

$V=\frac{4}{3}(3.14)(125)$

$V=523.6 m^3$

Use substitution to solve the linear system of equations

xenn [34]

we are given

system of equations

$y=4x$

$3x+5y=-46$

we can plug first equation into second equation

we get

$3x+5(4x)=-46$

Simplify left side

$3x+20x=-46$

$23x=-46$

Divide both sides by 23

and we get

$x=-2$

now, we can find y-value

$y=4*-2$

$y=-8$

so, our solution is

$(x,y)=(-2,-8)$ .............Answer
