Answer:
You can't have a single answer.
Step-by-step explanation:
An indiviual equation can't be solved if it has 2 variables.
You can, however, graph it.
The line will create all the possible sets of answers for the problem.
4/5 * 3 = 12/5 liters There are 2 cups in a liter so to find the root beer in cups, divide 12/5 by 2. You will get 12/10 cups which is 1.1 cups
35/8 = 4.376 5/3 = 1.666… 4.376/1.666…
Therefore 2.625 pieces
Answer: 3 + 7i
Step-by-step explanation:
Equation expanded: 12 + 5i - 9 + 2i // now simplfy
12 - 9 = 3
5i + 2i = 7i
// together, we get
3 + 7i
well, let's say that the first solution is 7 liters and has "x" percent of acid, how much acid total in it? well, 7x, <u>keeping in mind that "x" is a decimal form</u>.
likewise, the second solution is 3 liters and has 15% acid, so how much acid is there in that one? (15/100) * 3 = 0.45, so
