  B  -7/2

Step-by-step explanation:

The slope of the line is the coefficient of x when you solve for y.

  7x +2y = 5

  2y = -7x +5 . . . . . . . subtract 7x to isolate the y-term

  y = -7/2x +5/2 . . . . . divide by 2

The slope of the line is -7/2.

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
