Answer: C

Step-by-step explanation:

$\dfrac{x+2}{15} =\dfrac{x+1}{5}$

cross multiply: 5(x + 2) = 15(x + 1)

distribute: 5x + 10 = 15x + 15

-5x -5x

10 = 10x + 15

-15 -15

-5 = 10x

$\dfrac{-5}{10}=\dfrac{10x}{10}$

$-\dfrac{1}{2} =x$

Which unit of measurement would be appropriate for the volume of a sphere with a radius of 2 meters

Semenov [28]

The volume of a sphere is found with the following formula:

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

The radius is raised to a power of 3. Since the radius is 2 meters, this means that the volume would be measured in cubic meters.
