Replace “is” with =, “less than” with –, and “a number” with n to get 16 = 5 – n.
Replace “is” with =, “less than” with –, and “a number” with n to get 16 = 5 – n .

Replace “is” with =, “less than” with +, and “a number” with n to get 16 = n + 5.
Replace “is” with =, “less than” with +, and “a number” with n to get 16 = n + 5.

Answer 1

Here are the answers to your questions based on the statements provided.

Question 1

Responses:

1. The word “is” means equals.
2. This is an equation because it is written as a complete sentence.
3. The operation is addition.
4. This is an equation because two expressions are set equal to each other.

Note: “A number” is not a constant; it represents an unknown variable.

Question 2

Responses:

1. 8 = j - 4
2. Twelve is the sum of a number and six.
3. 5x = 45

Note: "30y" and "k + 46" are not complete equations.

Question 3

Responses: Replace “is” with =, “less than” with –, and “a number” with n to get 16 = n - 5.

Question 4

This statement represents: Eight is the quotient of a number and five.
The correct equation is: 8 = n / 5 (or alternatively, n / 5 = 8)

Question 5

Since you haven't provided the responses or options for the students, I can't evaluate them. If you provide the student responses, I can help determine which one correctly applied substitution.
