Rodney is to make hamburgers for the football game. he's made 10 hamburgers so far. his coach asked him to make at least 30 hamburgers but no more than 80. solve the inequality and interpret the solution.
30 ≤ x + 10 ≤ 80
20 ≥ x ≥ 70; rodney needs to make less than 20 more hamburgers or more than 70.
40 ≤ x ≤ 90; rodney needs to make at least 40 more hamburgers but no more than 90.
40 ≥ x ≥ 90; rodney needs to make less than 40 more hamburgers or more than 90.
20 ≤ x ≤ 70; rodney needs to make at least 20 more hamburgers but no more than 70.

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
