Answer:
4 > x
Step-by-step explanation:
5 (x + 3) - 4> 3x + 9 + 4x – 6
5x + 15 - 4 > 3x + 4x + 9 - 6
5x + 11 > 7x + 3
11 - 3 > 7x - 5x
8 > 2x
8/2 > x
4 > x
Hope this helps :D

Answer:
2.5 gal would have to be replaced with 100% bleach to get the right concentration.
Step-by-step explanation:
If we drain X gal from the tank and we replace it with X gal of 100% bleach we will have in the tank: 80-X gal of 4% bleach and X gal of 100% bleach.
We can calculate the final concentration of the solution using a weighted average of the volumens where the weights are going to be the concentrations of each one:
(7%)×(80) = (4%)×(80-X) + (100%)×(X)
560 = 320-4X+100X
240 = 96X
X=2.5 gal
