The first step to solving this is to multiply both sides of the equation by 3
8 + 10y = 9y - 12
now move the variable to the left side and change its sign
8 + 10y - 9y = -12
move the constant to the right side and change its sign
10y - 9y = -12 - 8
collect the like terms for y
y = -12 - 8 (it equals 1 when you subtract 10 from 9 which is the same is simply saying "y")
calculate the difference on the other side of the equals sign
y = -20
this means that the correct answer to your question is -20.

Answer:
Approximately 50.318 km.
Step-by-step explanation:
To find the diameter of a circle, you use the equation C = pi x d, where the d stands for diameter.
First, you'd plug in the 158 for C, so you have 158 = pi x d.
Since we are using 3.14, it would be 158 = 3.14 x d, and so then we'd divide both sides by 3.14 to isolate the variable d.
158/3.14 gives you approximately 50.3184713376, though rounded to the nearest thousandths, 50.318.
Answer:

Step-by-step explanation:
A spreadsheet is a useful tool for keeping track of the numbers. A picture of one is attached.
We have assumed that the dollar amount for housing computed in the first part remains the same (though the percentage changes). If that is not the case, you'll have to recompute.
Likewise, we assume that the "5%" retirement amount remains 5% of the nominal salary, rather than 5% of the salary after the mandatory retirement deduction. Similarly, we assume dance lessons remain at their original amount, and were not reduced when the company began taking mandatory retirement.
Feel free to build your own spreadsheet and recompute as needed for any assumptions I got wrong, or for any additional scenarios.
Answer:
The answer is 36 meters long.
Step-by-step explanation:
You start with the difference between 120 and 30 meters. 30 is 1/4 of 120, so all you do is do the opposite with 9. What's 4/1 times more than 9 and you get your answer.
I like the cute avatar and the answer is 13
