How do i do this! pls help ASAP, and pls show work too!

Step-by-step explanation:

Find the variable in the expression and see what has been done to it. Here, 'a' has been multiplied by c, and b has been subtracted from the product. Undo those operations in reverse order.

Undo the subtraction of b by adding b to both sides.

  g +b = ca -b +b

  g +b = ca . . . . . note b is no longer subtracted from the product

Undo the multiplication by dividing both sides by c.

  (g +b)/c = (ca)/c

  (g +b)/c = a

  a = (g +b)/c

The second problem is worked exactly the same way.

  u = 2x -2

  u +2 = 2x . . . . . add 2 to both sides

  (u +2)/2 = x . . . . divide both sides by 2

  x = (u +2)/2

step-by-step explanation:

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

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
