Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters
Hope this helped!!

Step-by-step explanation:
<h3>
Answer: angle Q = 75 degrees</h3>
Explanation:
The order of ABC and RPQ is important so we can match up the angles like so
- angle A = angle R .... first letters
- angle B = angle P .... second letters
- angle C = angle Q ... third letters
Meaning that angle Q = 75 since angle C is this measure.
Cent is by the hundred so one percent is 1/100 so .6%=6/1000
which can be reduced to 3/500
