Which of the following best describes the set of odd integers from –11 to –3? a. {–11, –9, –7, –5, –3} b. {–11, –9, –7, –3} c. null set d. {–11, –10, –9, –8, –7, –6, –5, –4, –3}

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
