Distributive property: → 
First do expand.

Then you subtract by 4 from both sides of an equation.

Simplify by equation.

Next, subtract by 2x from both sides of an equation.

Simplify.

You can also divide by 2 from both sides of an equation.

Finally, simplify by equation and dividing into the groups.

Answer: →

Answer:
Step-by-step explanation:
For the second column
1. 4*5+8=28
2. 4*5.5+8=30
3. 4*6+8=28
4. 4*6.5+8=34
5. 4*7+8= 36
6. 4*7.5+8=38
For the third column
1. 7*5-11=24
2. 7*5.5-11=27.5
3. 7*6-11=31
4. 7*6.5-11=34.5
5. 7*7-11=38
6. 7*7.5-11=41.5
Using proportions, it is found that the estimate of the the per capita consumption from 2011 was of 29.25 gallons.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The amount in 2012 was a increase of 5.3% from 2011, that is, 105.3% = 1.053 of x, and the consumption per capita was of 30.8 gallons, hence:
1.053x = 30.8
x = 30.8/1.053
x = 29.25 gallons.
