Answer:
10 liters of pure alcohol
Step-by-step explanation:
Create an equation where x is the number of liters of pure alcohol needed:
1x + (0.4)(20) = (20 + x)(0.6)
Simplify:
x + 8 = 0.6x + 12
Solve for x:
0.4x = 4
x = 10
So, 10 liters of pure alcohol have to be added
(5.)
13x + 5 = 83
-5 -5
13x =78
/13 /13
x = 6
(9.)
0.7 , 0.9 , 1.6 , 2.3 , 2.5
median = 1.6
