Let d = 0.825252525..., then

Therefore,
Answer:
5.2%.
Step-by-step explanation:
After 1 hour (60 / 100) * 700 = 420 gallons of beer have been exchanged.
So we have 420 gallons of 6% and 280 gallons of 4% after 1 hour.
So the strength at that time = (420* 6) + 280*4) / 700
= 5.2%.
<u>Answer</u>

<u>Detailed Explanation </u>
To simply answer this, since .189 has three digits we are going to be inserting 999 as the denominator since it is a repeating decimal.

We could simplify the answer!

Therefore, the answer would simply be 

<u>Always Remember </u>
In the future, always remember whenever you have a three digit decimal and the problem asks you to convert it into a fraction, you should always insert 1000 as the denominator (the numerator is basically the decimal without the decimal point) and simplify if necessary.
Answer:
x = 11
Step-by-step explanation:
Given :
AB = x + 5
BC = 2(x - 3)
AB = BC
AB = BC
x + 5 = 2(x - 3)
x + 5 = 2x - 6
5 + 6 = 2x - x
11 = x
x = 11
