Correct Answer
A. 2x+2Explanation
The given expression is 5x+2-3x. To simplify this expression, we combine like terms. The x terms, 5x and -3x, can be added together to give 2x. The constant terms, 2 and 0, can be added together to give 2. Therefore, the simplified expression is 2x+2.Rate this question:

8a+5a
Correct Answer
A. 4a+8Explanation
The expression 7a + 8 - 3a simplifies to 4a + 8. This is because when we combine like terms, we add the coefficients of the same variable. Here, the coefficients of 'a' are 7 and -3. So, when we subtract 3a from 7a, we get 4a. The constant term 8 remains unchanged. Therefore, the simplified expression is 4a + 8.Rate this question:

Correct Answer
A. 13yExplanation
When combining like terms, we add the coefficients of the terms with the same variable. In this case, we have 8y and 5y. Adding the coefficients 8 and 5 gives us 13. Therefore, the answer is 13y.Rate this question:

None
Correct Answer
A. 7x-5y+18Explanation
The given expression can be simplified by combining like terms. We can combine the terms with 'x' and the terms with 'y'. Combining the terms with 'x', we get -3x + 10x = 7x. Combining the terms with 'y', we get -5y. The constant terms 16 and 2 can be combined to give 18. Therefore, the simplified expression is 7x - 5y + 18.Rate this question:

-26x+3y-18
Correct Answer
A. 15Explanation
The given expression is simplified by combining like terms. By combining the terms -20x and -7x, we get -27x. Similarly, combining x and 3y, we get 4y. Combining -12, -6, and 15, we get -3. Therefore, the simplified expression is -27x + 4y - 3. However, this does not match any of the given answer choices. Therefore, the correct answer is not provided.Rate this question:

Correct Answer
A. 0Explanation
The given expression is 15y + 27 - 15y - 20 - 7. Simplifying this expression, we can combine like terms. The 15y and -15y cancel each other out, leaving us with 27 - 20 - 7. Simplifying further, we get 7 - 7, which equals 0. Therefore, the correct answer is 0.Rate this question:
