5f - 7 = 23

divide by 5 on each side

subtract 7 from each side

subtract 23 from each side

add 7 to each side

add 7 to both sides

then you are left with 5f=30

divide by 5 on both sides

you get f=6

Step-by-step explanation:

v[5/7] represents the volume of air inside a rubber ball with radius 5/7 units, such that

Step-by-step explanation:

Given: The volume of air inside a rubber ball with radius r can be found using the function.

Here volume is a dependent variable on radius (independent variable).

Therefore, the value of v[5/7]  represents the volume of air inside a rubber ball with radius 5/7 units.
