Please check these I'm not too good with algebraic expressions so i want to make sure I'm correct~ HELP ME AS SOON AS POSSIBLE!
You only have number 1 right.
Please take your time and go back and study your text book.

Are these still wrong Ms.Sue?
This is much better. Only 4 is still wrong.
For 5, I assume C is 18.
lol ok i will fix 4 one sec
ok #4 I think is C am i wrong?
Yes, number 4 is C.
ok i will send it in and tell u what i got
i missed 1 #5 was 18 but it was D not C
That's why I asked you about # 5.
Let's go through each question and solve them step by step:
1. 3w - 10w:
To simplify this expression, we need to combine like terms, which means we need to combine terms that have the same variable and the same exponent.
In this case, both terms have 'w' as the variable, so we can combine them.
3w - 10w is equal to (3 - 10)w, which simplifies to -7w.
Therefore, the correct answer is B, -7w.
2. y + 2y + 3z:
Again, we need to combine like terms, which means we combine terms with the same variable and exponent.
In this case, we have two 'y' terms and one 'z' term.
Adding the 'y' terms gives us 3y, so the expression becomes 3y + 3z.
Therefore, the correct answer is A, 3y + 3z.
3. 6r + r - 5r:
First, simplify within the parentheses: 6r + r becomes 7r.
Now, we have 7r - 5r, which simplifies to (7 - 5)r or 2r.
Therefore, the correct answer is A, 2r.
4. 5x + 2(x + 6):
Using the distributive property, we need to multiply 2 by both terms inside the parentheses.
So we have 5x + 2x + 2*6, which simplifies to 5x + 2x + 12.
Combining the like terms, the expression becomes 7x + 12.
Therefore, the correct answer is C, 7x + 12.
5. -3m + 3(m + 6):
Again, using the distributive property, we need to multiply 3 by both terms inside the parentheses.
So we have -3m + 3m + 3*6, which simplifies to -3m + 3m + 18.
Combining the like terms, the expression becomes 18.
Therefore, the correct answer is D, 18.
Based on the explanations above, here are the correct answers:
1) B, -7w
2) A, 3y + 3z
3) A, 2r
4) C, 7x + 12
5) D, 18
I hope this helps! Let me know if you have any further questions.
