What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Let the number be x.
I am thinking of a number. I multiplied this number by 3, subtracted 8, and doubled the result, then added 14.
First part:
2(3x - 8) + 14
6x - 16 + 14
6x - 2
Then I added 50% of what I had and then added 11.
Second part:
(6x - 2) + 50/100 (6x - 2) + 11
6x - 2 + 3x - 1 + 11
9x + 8
Then I divided by 5. After all that, I was left with 8.
Third part:
(9x + 8) / 5 = 8
9x + 8 = 40
Subtract 8 on both sides.
9x = 40 - 8
9x = 32
Divide both sides by 9.
x = 32/9
Thus,
The number that was started with is 32/9.

It takes 4.12 gallons of paint to paint a fence.
How much paint is needed for 1/5 of the fence?
[answer] gallons
Answers
The amount of paint needed for 1/5 of the fence is 0.824 gallons.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that;
Paint= 4.12gallons
Now,
To find the amount of paint needed for 1/5 of the fence, we can use the following proportion:
14.12=1/5x
where x is the unknown amount of paint. To solve for x, we can cross-multiply and get:
x=14.12×1/5
Simplifying, we get:
x=0.824
Therefore, by unitary method the answer will be 0.824 gallons.

A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for π. (PI)
Answers
Your answer should be:
66
Why...?
Simple.
First, you multiply 21 by 22/7. But to make this easier you have to fix in 'improper fraction.' and make it into an improper fraction. Which will become 3 1/7. Now you multiply 21 and 3 1/7. Which will equal 66. So, 66 is your answer.
