Exercise 20 Page 149

Substitute 0.1 into the given inequality and then simplify.

No.

Practice makes perfect
We can determine whether 0.1 is a solution by substituting it into the inequality and simplifying.
p + 1.4 ≤ 0.5
0.1 + 1.4 ? ≤ 0.5
1.5 ≤ 0.5 *
Since 1.5 is not less than or equal to 0.5, 1.4 is not a solution.
