Which values from the given replacement set make up the solution set of the inequality? 2b–4≥2 ; {1,2,3,4} {1,2} {3,4} {1,2,3} {2,3,4}

2b - 4 ≥ 2 ; [1,2,3,4]

Plug in each number for "b" in the inequality

2(1) - 4 ≥ 2

2 - 4 ≥ 2

-2 ≥ 2

1 is not a solution because -2 is not greater than or equal to 2.

2(2) - 4 ≥ 2

4 - 4 ≥ 2

0 ≥ 2

2 is not a solution because 0 is not greater than or equal to 2.

2(3) - 4 ≥ 2

6 - 4 ≥ 2

2 ≥ 2

3 is a solution because 2 is equal to 2.

2(4) - 4 ≥ 2

8 - 4 ≥ 2

4 ≥ 2

4 is a solution because 4 is greater than 2.

{3, 4} is your answer

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
