Exercise 33 Page 174

Substitute - 3 into the given inequality and then simplify.

Yes, see solution.

Practice makes perfect

We can determine whether n= - 3 is a solution by substituting it into the inequality and simplifying using the order of operations.

6÷ n ≤ - 5

n= - 3

6÷ ( - 3) ≤ - 5

a÷ b=a/b

6/- 3 ≤ - 5

Put minus sign in front of fraction

- 6/3 ≤ - 5

Calculate quotient

- 2 ≤ - 5 ✓

Since - 2 is less than or equal to - 5, this means that n= - 3 is a solution.
