Answer How many liters of a 20% acid solution should be mixed with 30 liters of 50% acid solution in order to obtain a 40% solution. ... x=15 liters 15*(.20 pure acid)=3 liters 30*(.50 pure acid)=15 liters That is 18 liters pure acid That is 45 liters solution *0.45 pure acid=18 liters.
Step-by-step explanation:
The absolute value inequality is |x - 6| < 12 and the complete points are Midpoint = 6 and Distance = 12
<h3>How to complete the inequality?</h3>
The inequality expression is given as
-6 < x < 18
The distance is calculated as:
Distance = |18 -(-6)|/2
Evaluate the difference
Distance = 12
The midpoint is calculated as:
Midpoint = 0.5 * (18 - 6)
Evaluate
Midpoint = 6
The absolute value inequality is represented as
|x - Midpoint| < Distance
So, we have
|x - 6| < 12
Hence, the absolute value inequality is |x - 6| < 12 and the complete points are Midpoint = 6 and Distance = 12

Answer:
(4, -3)
Step-by-step explanation:
You just divide each coordinate by 3.
Answer:
x= -6
Step-by-step explanation:
3x+4= 2 (x - 1)
3x+4= 2x -2
Subtract 4 from both sides of the equation
Simplify
Subtract 2x from both sides of the equation
Simplify
= -6
Answer:
Best deal is corner store
Step-by-step explanation:
LCM is 480 oz
480 oz of the Vending Machine would be £24 (0.60 x (480/12))
480 oz of the Corner Store would be £22.80 (0.95 x (480/20))
480 oz of Grocery store would be £23.25 (1.55 x (480/32))
