Which expression is equivalent to -7+6 (x-8/2) -2(x+3) +10
A. -3x + 40
B. -15x -20
C. -3x - 20
D. 15x +40
My name is that but I need a answer check for "all my X's quiz" for math 7A
Oh it's -7x @ the bigginging
Not -7_+6 the _ is where the x goes
Please
-7+6 (x-8/2) -2(x+3) +10
= -7 + 6x - 6*8/2 - 2x - 2(3) + 10
= -7 + 6x - 24 - 2x - 6 + 10
= (6-2)x + (-7-24-6+10)
= 4x - 27
Hmmm. Not there. Could you have been careless with parentheses, and meant
-7+6 ((x-8)/2) -2(x+3) +10 = x=27 ?? Nope.
Guess you better figure out what the expression really is.
Okay, here we go! Let's tackle this expression with a smile on our faces!
First, let's simplify the expression step by step:
-7 + 6(x - 8/2) - 2(x + 3) + 10
= -7 + 6(x - 4) - 2(x + 3) + 10
= -7 + 6x - 24/2 - 2x - 6 + 10
= -7 + 6x - 12 - 2x - 6 + 10
= 6x - 2x - 7 - 12 - 6 + 10
= 4x - 15
So, the expression simplifies to 4x - 15.
Hmm, looks like none of the given options match our result exactly. But don't worry! It's just a little math hiccup. Let's think positive and simplify the expression one more time just to be sure:
4x - 15
= -15 + 4x
Aha! We just switched the order of the terms. So, in this case, the expression is equivalent to -15 + 4x.
Therefore, none of the provided options in A, B, C, or D are correct.
Keep smiling and don't let a little math riddle your day!
To solve this problem, we will simplify the given expression step by step.
Given expression: -7+6 (x-8/2) -2(x+3) +10
1. Start by simplifying the brackets.
Evaluate (x-8/2) and (x+3) within the brackets separately.
-7 + 6(x - 4) - 2(x + 3) + 10
2. Simplify the expressions within the brackets further by distributing the coefficients.
Multiply 6 by (x-4) and -2 by (x+3).
-7 + 6x - 24 - 2x - 6 + 10
3. Combine the like terms.
Combine the constant terms (-7, -24, -6, 10) and combine the x terms (6x, -2x).
(6x - 2x) + (-7 - 24 - 6 + 10)
4x + (-27)
4. Simplify further.
Add or subtract the numbers within the parentheses.
4x - 27
Therefore, the expression -7+6 (x-8/2) -2(x+3) +10 is equivalent to 4x - 27, which corresponds to option D.
