Hey, 1 is incorrect. When you see the words, More Than you switch the problem around. The question is 5 more than D. First you have to KNOW what D is, right? So the answer to the question would be D+5.

Oh, okay. Thanks!

You're welcome.

algebraic expression represents “the sum of a number and 9

The sum of one and the product of one and a number xxx

Sure! Here's how you can check these algebraic expressions:

1. To check the first expression, 5 + D, you can substitute a value for D and evaluate the expression. For example, if we let D = 3, then 5 + D = 5 + 3 = 8.

2. To check the second expression, 2*W, you can substitute a value for W and evaluate the expression. For example, if we let W = 4, then 2*W = 2*4 = 8.

3. To check the third expression, 60*W, you can substitute a value for W and evaluate the expression. For example, if we let W = 5, then 60*W = 60*5 = 300.

4. To check the fourth expression, N - 18, you can substitute a value for N and evaluate the expression. For example, if we let N = 25, then N - 18 = 25 - 18 = 7.

5. To check the fifth expression, 14 - M, you can substitute a value for M and evaluate the expression. For example, if we let M = 10, then 14 - M = 14 - 10 = 4.

6. To check the sixth expression, 2*C + 16, you can substitute a value for C and evaluate the expression. For example, if we let C = 6, then 2*C + 16 = 2*6 + 16 = 12 + 16 = 28.

7. To check the seventh expression, 3*N - 8, you can substitute a value for N and evaluate the expression. For example, if we let N = 10, then 3*N - 8 = 3*10 - 8 = 30 - 8 = 22.

8. To check the eighth expression, R + 12, you can substitute a value for R and evaluate the expression. For example, if we let R = 7, then R + 12 = 7 + 12 = 19.

9. To check the ninth expression, N/5, you can substitute a value for N and evaluate the expression. For example, if we let N = 20, then N/5 = 20/5 = 4.

10. To check the tenth expression, 15/Z, you can substitute a value for Z (except for Z=0, as division by zero is undefined) and evaluate the expression. For example, if we let Z = 3, then 15/Z = 15/3 = 5.

11. To check the eleventh expression, 3 - A, you can substitute a value for A and evaluate the expression. For example, if we let A = 2, then 3 - A = 3 - 2 = 1.

12. To check the twelfth expression, M - 49, you can substitute a value for M and evaluate the expression. For example, if we let M = 60, then M - 49 = 60 - 49 = 11.

By substituting different values for the variables and evaluating the expressions, you can check if the algebraic expressions are correct.

2. 2W

3. 60W

All of your answers are correct. However the standard way of writing a multiplication problem is the way I showed you above.
