Answer 2

(х-2,81)+(3,2-х)=х-2,81+3,2-х=0,39

Answer 3

Sum of Expressions and Simplification

To find the sum of the expressions x-2.81 and 3.2-x and simplify it, we can follow these steps:

1. Find the Sum of the Expressions: - The sum of the expressions x-2.81 and 3.2-x is obtained by adding them together: (x-2.81) + (3.2-x).

2. Simplify the Sum: - After finding the sum, simplify the expression to obtain the final result.

Let's proceed with these steps to find the sum and simplify the given expressions.

Finding the Sum of the Expressions

The sum of the expressions x-2.81 and 3.2-x is: (x-2.81) + (3.2-x).

Simplifying the Sum

To simplify the sum, we can combine like terms: (x-2.81) + (3.2-x) = x - 2.81 + 3.2 - x.

Now, let's simplify the expression: (x - x) + (3.2 - 2.81) = 0.39.

So, the sum of the expressions x-2.81 and 3.2-x simplifies to 0.39.

This is the result after finding the sum and simplifying the given expressions.
