63. $2 (r - 4) + 5 鈮� 9$

Short Answer

Expert verified

The solution of the given inequality is $r 鈮� 6$ .

Step by step solution

– State the concept

Solving an inequality means modifying the inequality so that the variable is isolated. It is essentially finding the range of values of the variable for which the given inequality is satisfied.

– List the given data

The given inequality is $2 (r - 4) + 5 鈮� 9$ .

– Solve the inequality

$2 (r - 4) + 5 鈮� 9$ (Given inequality)

$2 (r - 4) + 5 - 5 鈮� 9 - 5$ (Subtract 5 from both sides of the inequality)

$2 (r - 4) 鈮� 4$ (Simplify)

$\frac{2 (r - 4)}{2} 鈮� \frac{4}{2}$ (Divide both sides of the inequality by 2)

$r - 4 鈮� 2$ (Simplify)

$r - 4 + 4 鈮� 2 + 4$ (Add 4 to both sides of the inequality)

$r 鈮� 6$ (Simplify)

So, the solution of the given inequality is $r 鈮� 6$ .
