Simplify the expression:
8(2x - 3) - 6x = 8×2x - 8×3 - 6x = 16x - 24 - 6x = 10x - 24
for x=3
put value of "x" to the expression:
<u>10×3 - 24 = 30 - 24 = 6</u>
Answer:

And we know that the level is decreasing 20% each day so then we can use the following model for the problem

Where t represent the number of days and L the level for this case we want to fnd the level after two days so then t =2 and replacing we got:

Step-by-step explanation:
For this case we know that the initial volume of water is:

And we know that the level is decreasing 20% each day so then we can use the following model for the problem

Where t represent the number of days and L the level for this case we want to fnd the level after two days so then t =2 and replacing we got:

35=(5+2)+4
35=7+4
35=11
false so their is no answer
