I apologize for the confusion. Let's simplify the expression again.
-1/2 (-6+3)
First, we need to simplify the expression inside the parentheses:
-1/2 (-6+3) = -1/2 (-3)
Now, we can multiply the fraction by the number inside the parentheses:
-1/2 (-3) = -1/2 * -3
When we multiply a negative number by a negative fraction, the result is positive:
-1/2 * -3 = 3/2
Therefore, the simplified expression is 3/2.

(5y - 1) + (-2y + 4)
(5y - 1) + (-2y + 4)
To simplify the expression (5y - 1) + (-2y + 4), we can combine like terms.
First, we remove the parentheses and combine the y terms and the constant terms separately:
5y - 1 + (-2y + 4)
= 5y - 2y - 1 + 4
= 3y + 3
Therefore, the simplified form of (5y - 1) + (-2y + 4) is 3y + 3.

Therefore, the simplified form of (3x - 8) + (2x + 5) - (4x - 8) is x + 5.
Which expression is equivalent to 2.2 - 0.5 (0.6x - 1.8)
To find the expression equivalent to 2.2 - 0.5 (0.6x - 1.8), we can start by simplifying the expression inside the parentheses:
0.6x - 1.8
Then, we can distribute the -0.5 to each term inside the parentheses:
-0.5 * 0.6x = -0.3x
-0.5 * -1.8 = 0.9
So, the expression becomes:
2.2 - 0.3x + 0.9
Next, we can combine like terms:
2.2 + 0.9 - 0.3x = 3.1 - 0.3x
Therefore, the expression equivalent to 2.2 - 0.5 (0.6x - 1.8) is 3.1 - 0.3x.
0.6x - 1.8
Then, we can distribute the -0.5 to each term inside the parentheses:
-0.5 * 0.6x = -0.3x
-0.5 * -1.8 = 0.9
So, the expression becomes:
2.2 - 0.3x + 0.9
Next, we can combine like terms:
2.2 + 0.9 - 0.3x = 3.1 - 0.3x
Therefore, the expression equivalent to 2.2 - 0.5 (0.6x - 1.8) is 3.1 - 0.3x.
