Question

seventeen is eight more than a number. statements are true? check all that apply. a. this is an equation because it is written as a complete sentence. b. this is an equation because two expressions are set equal to each other. c. “a number” is the constant. d. the operation is addition. e. the word “is” means equals. f. the constants are 17 and 8.

Explanation:

• An equation is a statement where two expressions are equal. Here, we can translate "Seventeen is eight more than a number" to $17=x + 8$, where two expressions are set equal. So B is true.
• "Is" in math - language often means "equals", so E is true.
• The operation is addition as we have a number plus 8 on one side, so D is true.
• 17 and 8 are fixed values, so they are constants, so F is true.

Answer:

B. This is an equation because two expressions are set equal to each other.
D. The operation is addition.
E. The word "is" means equals.
F. The constants are 17 and 8.
