am I correct?
Let's go through each question one by one to check your answers:
1. 3w - 10w:
To simplify this expression, we subtract the coefficients of the variables. In this case, we have 3w - 10w, which gives us -7w as the correct answer. So your answer of -7w is correct.
2. y + 2y + 3z:
To simplify this expression, we combine like terms. We have y and 2y, which both have the same variable 'y'. When adding them together, we get 3y. Then we add 3z to get the final answer as 3y + 3z. Your answer of 2y + 3z is not correct.
3. 6r + r - 5r:
To simplify this expression, we again combine like terms. We have 6r and r as positive terms, and -5r as a negative term. Combining them together, we have 7r - 5r = 2r. So your answer of 2r is correct.
4. 5x + 2(x + 6):
To simplify this expression, we apply the distributive property by multiplying 2 with both terms inside the parentheses. This gives us 5x + 2x + 12. Combining like terms, we have 7x + 12. So your answer of 7x + 12 is correct.
5. -3m + 3(m + 6):
To simplify this expression, we again apply the distributive property by multiplying 3 with both terms inside the parentheses. This gives us -3m + 3m + 18. Combining like terms, we can see that the variable terms (-3m and 3m) cancel each other out, leaving us with the constant term 18. So your answer of 18 is correct.
Overall, you have 4 out of 5 correct answers. The only incorrect answer is for question 2, which should be 3y + 3z instead of 2y + 3z. Keep up the good work!
1. Correct
2.
y + 2 y + 3 z = ( y + 2 y ) + 3 z = 3 y + 3 z = 3 ( y + z )
3. Correct
4. Correct
5. Correct
here's number two again
y + 2y + 3z
1. 2y + 3x
2. 3y + 3z
3. 2y2 + 3z
4. 3yz
Are you kidding?
y + 2 y + 3 z = 3 y + 3 z
