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

Hope it helps :)

Answer:

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.
