The value of 3 - 22 tenths or 3 - 2.2 is determined as 0.8.
Tenths are a way of expressing fractional parts of a whole number, where one whole is divided into ten equal parts.
So, if we have 22 tenths, it means we have 22 out of the 10 equal parts of a whole. This can also be written as 2.2, where the number after the decimal point (2) represents the number of tenths.
To find the value of 3 - 22 tenths, we can subtract 22 tenths from 3 as shown below.
The given expression in tenths;
= 3 - 22 tenths
The solution is calculated as follows
= 3 - 2.2
= 0.8
Thus, the value of 3 - 22 tenths or 3 - 2.2 is determined as 0.8.

The solution to the equation 4x - 9 = 11 is x = 5.
We will use the appropriate algebraic operations to isolate the variable x in order to solve the equation 4x - 9 = 11 for x.
Here is the detailed answer:
Let's start with the formula: 4x – 9 = 11.
To get rid of the constant term on the left side, add 9 to both sides of the equation:
4x - 9 + 9 = 11 + 9.
When we simplify, we obtain 4x = 20.
To separate x, divide both sides of the equation by 4:
(4x)/4 = 20/4.
To further simplify, we have x = 5.
As a result, x = 5 is the answer to the equation 4x - 9 = 11.
