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

Problem 3

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

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

Problem 5

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

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

Work Shown:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
