What is Simplification?

Simplification in mathematical terms is a process to convert a long mathematical expression in simple and easy form.

Let the required positive number is x,

Since, 3.5 times of the number x is equal to sum of number x and 0.5.

The above expression can be written as,

(3.5) x = x + 0.5

3.5x - x = 0.5

2.5 x = 0.5

x = 0.2

The required number is 0.2.

Answer 2

Answer: let x = the number

3.5x = x + 0.5
3.5x - x = 0.5
2.5x = 0.5
x = 0.5/2.5
x = 0.2

therefore the number is 0.2

What is the answer to the equation 5+2(x-1)=12

Answers

$5+2(x-1)=12 \n \n 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \n \n 2(x - 1) = 7 \ / \ simplify \n \n x - 1 = (7)/(2) \ / \ divide \ each \ side \ by \ 2 \n \n x = (7)/(2) + 1 \ / \ add \ 1 \ to \ each \ side \n \n x = (9)/(2) \ / \ simplify \n \n$

So, the answer to this problem is x = 9/2 or x = 4.5.

5+2(x-1)= 12
So you need to get rid of parentheses, which is that you have to distribute.
5+2x-2= 12
-5 -5 (Inverse)
2x-2= 7
+2 +2 (Another inverse)
2x= 9
2 2 (Divide)

x= 4.5
----------------------
Check
5+2(4.5-1)=12
5+2(3.5)=12
5+7=12
12=12

A dispenser holds 5652 cm3 of liquid soap and is now full. The radius of the dispenser is 7.5 cm. What is the difference between the height of the soap in the full dispenser and the height when 4239 cm3 of soap remains in the dispenser? Use 3.14 to approximate pi.

Answers

30cm is the difference between the height of the soap in the full dispenser and height of the remaining soap.

The formula for cylindrical height is:

  Area
  --------   - r
2 * π * r

Cylindrical height of full dispenser.

  5652 5652
--------------------- - 7.5 = ------------ - 7.5 = 120 - 7.5 = 112.50
2 * 3.14 * 7.5 47.1

Cylindrical height of dispenser with lesser liquid soap

4239 4239
-------------------- - 7.5 = ------------ - 7.5 = 90 - 7.5 = 82.50
2 * 3.14 * 7.5 47.1

Cylindrical height of full soap      112.50
Cylindrical height of lesser soap     - 82.50
Difference in height of soap content 30.00
