Exercise 25 Page 388

Substitute 10 into the given inequality and then simplify.

No

Practice makes perfect
We can determine whether 10 is a solution by substituting it into the inequality and simplifying.
6 ≤ b/2
Substitute

b= 10

6 ? ≤ 10/2
CalcQuot

Calculate quotient

6≤5 *
Since 6 is not less than or equal to 5, we got a false statement. This means that b=10 is not a solution of the inequality.
