Sample Response: Replace keywords with variables, numbers, and operations. Less than is subtraction, and the quotient is division. Order matters with subtraction and division. The expression is

-13. To evaluate is the expression, substitute 2 in for the variable, and then use order of operations to simplify. The value when n = 2 is 7.
explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
explain how you know that an estimated quotient of 6 is too large for 416/73

Sample Response: Replace key words with variables, numbers, and operations. More than is addition, product is multiplication, and decreased by is subtraction. The constants are 1, 7, and 5. The expression is 1 + 7n – 5. To evaluate the expression, substitute 6 in for the variable, and then use order of operations to simplify. The value when n = 6 is 38.
they are the same they are both 9
Yes. The quotient of two non-zero integers is a rational number.
You evaluate the data you have then explain what it means. "evaluate" - to examine, appraise, judge carefully, fix the worth of something. "explain" - to make something or the meaning of something clear to somebody else.

you have to figure it out
Multiply the quotient times the dividend and then add on the remainder to the product.
