Let's change all of them into seconds so it is easier to compare:
Pamela: 51 seconds.
Lucy: 3/5 minute x 60 = 36 seconds
Kady: 8 minutes x 60 = 480 seconds
Thus, Kady can stay underwater the longest.
First subtract 12 from both sides, then subtract 2x from both sides, multiply both sides by -1, then divide by 4.
x > 3.5
Answer:

Step-by-step explanation:
Remark
For every 3 units for NP will be 4 units. You can set up a proportion.
