3(2y - 4) = 8y + 9 - 9y

Distribute 3:
6y - 12 = 8y + 9 - 9y

Combine like terms:
6y - 12 = -y + 9

7y - 12 = 9

7y = 21

Divide both sides by 3:
y = 3

The first step for solving this equation is to distribute 3 through the parenthesis.
6y - 12 = 8y + 9 - 9y
Collect the like terms with y.
6y - 12 = -y + 9
Move the variable to the left side and then change its sign.
6y + y - 12 = 9
Now move the constant to the right side and change its sign.
6y + y = 9 + 12
Add the terms on the left side of the equation.
7y = 9 + 12
Add the numbers on the right side.
7y = 21
Lastly,, divide both sides of the equation by 7 to find your final answer.
y = 3
This means that y = 3 is the correct answer to your question.

Question
Data: (12 ,8 , 6 , 12 , 16 , 12 ) median ............. mode......
Solution 1
Ascending order=  6, 8, 12, 12, 12, 16

No of observations (n) = 6
Median = Mean of the values of (n/2) and (n/2+1)
= Mean values of 3rd and 4th values
= 12+12/2
= 12
Therefore, median = 12

Mode = Most number of observations= 12
Solution 2
Your data is (12,8,6,12,16,12) for median and mode you take the least to greatest. Median = Middle So you take the Middle number your data table should look like this: (6,8,(12,+12),12,16) so the median is 12+12/How many numbers that are in the middle so you get the number 12.
For the mode just Think Mode is Most Whatever number that is the most in the Data (6,8,12,12,12,16) so 12 is the mode for the answer. and 12 is the median. Hope this Helps

Question
The town of Springfield, USA has a population of 9900 people. The population is growing at a rate of 2.3%, each year. Which expression gives the population 7 years from now?
Solution 1
The expression would be:  9900(1.023)^7

This is an example of an exponential equation. They are in the form y = ab^x. A is the starting value and b is the rate of change.

The rate is 1.023 because we are adding on 2.3% each time.

Question
What is the difference between volume surface area and area
Solution 1
Answer: Surface area is just what you can see. The outer part. The area is the whole thing. Even the inside, not just what you can see.

Explanation/Reasoning:
Surface area is the outside layer, or the uppermost part. It is what surrounds it. The area is the whole thing. Even what you cannot see.

-DustinBR
Solution 2
The area is the same as the surface area.
The volume measures the space inside a solid shape.
The surface area is the "face" of a solid shape. The measurement of the outside of the solid shape.
