SOLUTION: I need to solve the problem:
5(n-7)n is less than or equal to 20
This is my solution but I'm not sure it is correct:
5(n-7)n< or = 20
5*n-5*7n< or = 20
5n-35n< or = 20
-30n

Question 137484: I need to solve the problem:
5(n-7)n is less than or equal to 20
This is my solution but I'm not sure it is correct:
5(n-7)n< or = 20
5*n-5*7n< or = 20
5n-35n< or = 20
-30n< or = 20
-30n/-30 < or = 20/-30
n < or = -2/3
The questions is from a worksheet called 7-7 Practice Writing Inequalities Student Edition Glencoe/McGraw-Hill pages 355-357
You can put this solution on YOUR website! I need to solve the problem:
5(n-7)n is less than or equal to 20
This is my solution but I'm not sure it is correct:
5(n-7)n< or = 20
5*n-5*7n< or = 20
5n-35n< or = 20
-30n< or = 20
-30n/-30 < or = 20/-30
Comment: When you multiply or divide both sides of an inequality by a negative
number the inequality sign is reversed.
n >=-2/3
