Which of the following expressions are not equivalent to the expression 2x + 2 - 5x + 7 - 3? Select all that apply.
(1 point)
2x + 11 - 5x
-3x + 6
-
3x - 6
2(x + 1)- 5x + 4
2(x + 1)- 52 5 over 2x + 2
Please explain
The original expression is 2x + 2 - 5x + 7 - 3.
To determine which expressions are not equivalent, we can simplify each expression and compare them to the original expression.
Expression 1: 2x + 11 - 5x
Simplifying this expression by combining like terms, we get 2x - 5x + 11 = -3x + 11
Expression 2: -3x + 6
This expression is already simplified.
Expression 3: 3x - 6
This expression is not equivalent to the original expression because the sign in front of 3x is positive, whereas it should be negative to match the original expression.
Expression 4: 2(x + 1) - 5x + 4
Simplifying this expression by distributing 2 to x + 1 and combining like terms, we get 2x + 2 - 5x + 4 = -3x + 6
Expression 5: 2(x + 1) - 52 5 over 2x + 2
This expression seems to contain a typing error, as it is not clear what the intended calculation is. Therefore, it is not possible to determine whether it is equivalent to the original expression.
So, the expressions that are not equivalent to the original expression are:
-3x + 6
3x - 6
2x + 2 - 5x + 7 - 3. What is the answer for this explain please
To simplify the given expression, we need to combine like terms.
First, let's combine the x terms: 2x - 5x = -3x.
The expression now becomes: -3x + 2 + 7 - 3.
Next, let's combine the constant terms: 2 + 7 - 3 = 6.
The simplified expression is now: -3x + 6.
How is -3x + 6 not equivalent if it’s the answer?
Apologies for the confusion. You are correct. The expression -3x + 6 is indeed equivalent to the given expression 2x + 2 - 5x + 7 - 3. I apologize for the error in my initial response. Thank you for pointing it out.
Then what are the answers that aren’t equivalent to 2x + 2 - 5x + 7 - 3.
2x + 11 - 5x
-3x + 6
3x - 6
2(x + 1)- 5x + 4
2(x + 1)- 52 5 over 2x + 2
The expressions that are not equivalent to 2x + 2 - 5x + 7 - 3 are:
3x - 6
2(x + 1) - 52 5 over 2x + 2
These two expressions are not equivalent to the given expression because they simplify to different expressions.
