Since 10% = 0.10 by moving the decimal two spots to the left, we can say that 0.10L is the amount of alcohol with 10% concentration in L liters. Similarly, 0.60L is 60% for L liters and 0.30L is the amount of liters with 30%. If the amount of 10% alcohol solution in liters is x and the 60% in y, we get 0.10x+0.60y=0.30L due to that the liters add up to get a 30% amount of alcohol (this equation represents the amount of alcohol). Next, x+y=L. Since we know that we have 90 liters of 0.60, y=90 and we have
0.10x+54=0.30L
x+90=L. Plugging x+90 for L, we get 0.10x+54=0.3(x+90)=0.3x+27. Subtracting 27 and 0.1x from both sides, we get 0.2x=27. Next, we can multiply both sides by 5 (since 1/0.2=5) to get x=135 liters
Answer:
Infinity
Step-by-step explanation:
Topic: Fraction and relations:
<u><em>Your domain (Input to a fraction, usually known as your "x") can be any Real number.</em></u>
But, when you are dealing with <em>a fraction</em> or <em>even</em><em> square roots</em> you have to be careful because:
You cannot have a ZERO as your <em>denominator </em>and you cannot have NEGATIVE number<em> inside</em> of the square root.
The 2 problems can have infinite solution because it is not a fraction or square root problem and it doesn't break the 2 rules mentioned above.
