It's p = 6/(x+a).
Multiply both sides by p to get 6 = p(x+a), then divide both sides by (x+a) to get 6/(x+a) = p.
Step-by-step explanation:
If she is able to achieve her aim, then the robot is very efficient, as it uses as low as 49 joules in filtering 343 litres of air and water.
It will now be a question of what time the robot is able to achieve this feat, if it is able to do it in a time that matches the quality of the work it does, then it will be reasonable to call the robot efficient, and fast too.

Step-by-step explanation:
80 - 3.50x ........ (i)
70 - 3x ..............(ii)
Set them equal;
80 - 3.50x = 70 - 3x
Solve for x. 80-70 =3.50x - 3x
10=0.50x
20=x
There will be 20 days out of the 30-day period until the cards will be equal in value.
