1. hamburger patties are sold in packs of 8. sampson bought 19 packs of hamburger patties. he is hosting a barbecue tonight.

which equation could sampson use to calculate the number of hamburgers he will be able to make?
$x + 8 = 19$ (with a cross mark on it)

Explanation:

Step1: Solve the inequality \( r - 4.5 \geq 7 \)

To isolate \( r \), add \( 4.5 \) to both sides of the inequality.
\( r - 4.5 + 4.5 \geq 7 + 4.5 \)

Step2: Simplify both sides

Simplifying the left side gives \( r \), and simplifying the right side: \( 7 + 4.5 = 11.5 \). So we get \( r \geq 11.5 \).

Answer:

d. \( r \geq 11.5 \)
