3(2y - 4) = 8y + 9 - 9y

Distribute 3:

6y - 12 = 8y + 9 - 9y

Combine like terms:

6y - 12 = -y + 9

Add y to both sides:

7y - 12 = 9

Add 12 to both sides:

7y = 21

Divide both sides by 3:

y = 3

Distribute 3:

6y - 12 = 8y + 9 - 9y

Combine like terms:

6y - 12 = -y + 9

Add y to both sides:

7y - 12 = 9

Add 12 to both sides:

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.

Let me know if you have any further questions.

Question

the temperature last night was 10 degrees below 0. The next morning by 9 a.m. the temperature had risen 12 degrees. what was the temperature at 9 a.m.?

Solution 1

It was 2 degrees.................................................................................................................................................................................

Solution 2

It was two degrees at 9am

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**

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,

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

20 divided by X is 100, what does X equal?

Solution 1

20/ X= 100

⇒ X= 20/100 (inverse operation)

⇒ X= 1/5

**Final answer: X= 1/5**

⇒ X= 20/100 (inverse operation)

⇒ X= 1/5

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

Explanation/Reasoning:

-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.

Question

3.45, 3 2/5, 3 2/3 the number with the least value is

Solution 1

Change all to decimal:

3.45 = 3.45

3 2/5 = 3.4

3 2/3 = 3.6666

**The lowest value is 3 2/5.**

Hope this helped☺☺

3.45 = 3.45

3 2/5 = 3.4

3 2/3 = 3.6666

Hope this helped☺☺

Solution 2

3 2/5=3.40

3.45

3 2/3=3.66

3.45

3 2/3=3.66

Question

Volume of rectangular prism
Base= 1.5 by 3
Height= 6.4

Solution 1

Volume = base area x height

Volume = 1.5 x 3 x 6.4 = 28.8 unit³

**Answer: 28.8 unit³**

Volume = 1.5 x 3 x 6.4 = 28.8 unit³

Solution 2

The volume is 28.8 and you may find that out by using the formula lwh
