A chemist has three different acid solutions. The first acid solution contains 15 % acid, the second contains 30 % and the third contains 50 % . They want to use all three solutions to obtain a mixture of 144 liters containing 25 % acid, using 3 times as much of the 50 % solution as the 30 % solution. How many liters of each solution should be used?

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
