Step-by-step explanation:
Answer is 15%
You have to do a proportion
12. = x
80 100 and u have to cross multiply
80x = 1200
80. 80
then divide 1200÷80=15
The answer is 9 because if you put those numbers in a life from smallest to biggest and take one off each side your left with 9
<span>.75(x+3)=.5(3)+x
</span><span> You already have 3 liters, and you are going to add x liters.
50% (.5) of the 3 liters is acid, and 100% (1) of the added x liters is acid. You will end up with (3+x) liters.
If you have been assigned this problem, you should be able to solve this equation...
