Answer:
6 cases
Step-by-step explanation:
Kendra wants a total of 160 water bottles
She already has 16 water bottles. So you can subtract 16 from 160 or
160-16 = 144
Then since there are 24 water bottles in a case, you need to divide 144 by 24 or 144÷24 = 6

Answer:
the amount of time until 23 pounds of salt remain in the tank is 0.088 minutes.
Step-by-step explanation:
The variation of the concentration of salt can be expressed as:
being
C1: the concentration of salt in the inflow
Qi: the flow entering the tank
C2: the concentration leaving the tank (the same concentration that is in every part of the tank at that moment)
Qo: the flow going out of the tank.
With no salt in the inflow (C1=0), the equation can be reduced to
Rearranging the equation, it becomes
Integrating both sides
It is known that the concentration at t=0 is 30 pounds in 60 gallons, so C(0) is 0.5 pounds/gallon.
The final equation for the concentration of salt at any given time is
To answer how long it will be until there are 23 pounds of salt in the tank, we can use the last equation:

Answer:
x > 6
Step-by-step explanation:
6x + 2x > 6 (x + 2)
8x > 6 (x + 2)
8x > 6x + 12
<u>-6x -6x</u>
2x/2 > 12/2
x > 6
