Which expression is equivalent to 2.2 - 0.5 (0.6x - 1.8)?
2.2 - 0.3x + 0.9
To find the expression that is equivalent to 2.2 - 0.5(0.6x - 1.8), we will start by simplifying the expression inside the parentheses.
Step 1: Distribute -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
Step 2: Combine like terms:
2.2 + 0.9 - 0.3x
Step 3: Simplify by adding the numbers:
2.2 + 0.9 = 3.1
The final equivalent expression is: 3.1 - 0.3x
To find an equivalent expression for 2.2 - 0.5(0.6x - 1.8), we need to simplify the expression by performing the distributed multiplication and combining like terms.
Step 1: Distribute -0.5 across the terms inside the parentheses:
-0.5 * 0.6x = -0.3x
-0.5 * -1.8 = 0.9
The expression becomes: 2.2 - 0.3x + 0.9.
Step 2: Combine the constant terms (2.2 and 0.9):
2.2 + 0.9 = 3.1
The equivalent expression is: 3.1 - 0.3x.
