Answer:

$\boxed{\bold{x=-84}}$

Explanation:

Multiply Both Sides By 8:

= $\bold{8\cdot \frac{3}{8}\left(2x-\frac{8}{3}x\right)=21\cdot \:8}$

Simplify:

= $\bold{-2x=168}$

Divide Both Sides By -2:

= $\bold{\frac{-2x}{-2}=\frac{168}{-2}}$

Simplify:

= $\bold{x=-84}$

Nat2105 [25]

Corrected Question

The volume of air inside a rubber ball with radius r can be found using the function V(r) = four-thirds pi r cubed. What does V(5/7) represent?

Answer:

(B)the volume of the rubber ball when the radius equals five-sevenths feet

Step-by-step explanation:

The Volume of a sphere of radius r can be found using the formula:

$V(r)=\dfrac43 \pi r^3$

Therefore comparing the expression: $V(\dfrac57)$ with V(r):

$Radius, r=\dfrac57$

Thus, $V(\dfrac57)$ is the volume of a ball of radius $\dfrac57$ feet.

The correct option is B.
