What is the midpoint of the segment shown below?

Option D

Step-by-step explanation:

→ Add the x-coordinates together divide by 2 and then add the y-coordinated together and then divide by 2

- 1 + -6 = -1 - 5 = -7 ÷ 2 = -3.5

5 + -2 = 3 ÷ 2 = 1.5

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
