You need to add 2 L of the 75% mixture to get a mixture that is 60% antifreeze.
<h3>What is an antifreeze?</h3>
Anti freeze is a substance that is added in order to prevent a liquid from freezing. An antifreeze is usually an ionic substances that is used during the winter to prevent the freezing of a liquid.
Now;
Forming the equation;
0.75*x+0.5*3=0.6(3+x)
Hence;
0.75*x+1.5=1.8+0.6x
Therefore;
0.75x-0.6x=1.8-1.5
We obtain;
0.15x=0.3
Then;
x=2L

2 quarters, 3 dimes, 4 pennies...total of 9 coins
probability of first drawing a dime = 3/9 reduces to 1/3
without replacement (means u have only 8 coins now)
probability of then drawing a quarter = 2/8 reduces to 1/4
probability of both : 1/3 * 1/4 = 1/12 or 8.3%
Make an inequality representing both constraints.
