1) When it says more than, then you have to switch it so it will be 7n + 1 instead of 1+7n. 2) Because you then have to subtract by 5 you have to put the 7n + 1 in parentheses so it reads (7n + 1) - 5 3) And then to evaluate you just have to substitute n for 6 4) 7 * 6 = 42; 42+1 = 43; 43-5 = 38 5) The answer to this expression would be 38
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.
