Question

WiFi is stupid and so is online classes thanks for the help everyone in advance!

Answer 1

Problem 3

Camille is correct

You subtract 4x from both sides, then divide both sides by -2 to fully isolate y.

===============================================

Problem 4

Multiply both sides by r to get

2mr = p-q

which is the same as

p-q = 2mr

The last step is to add q to both sides leading to this final answer

p = 2mr+q

================================================

Problem 5

Answer: $r = \sqrt[3]{\frac{3V}{4\pi}}$

This is the cube root of (3V)/(4pi)

----------------

Work Shown:

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