Question

solve for r.
4r ≥ 8

Explanation:

Step1: Divide both sides by 4

To solve for \( r \) in the inequality \( 4r \geq 8 \), we divide both sides of the inequality by 4. Since 4 is a positive number, the direction of the inequality sign remains the same.
\[
\frac{4r}{4} \geq \frac{8}{4}
\]

Step2: Simplify both sides

Simplifying the left - hand side, \( \frac{4r}{4}=r \), and simplifying the right - hand side, \( \frac{8}{4} = 2 \). So we get \( r\geq2 \).

Answer:

\( r\geq2 \)
