If mrs. kenner uses 1.28 cups of butter in a cookie recipe the recipe made 16 equally sized cookies how much butter is in each cookie?

0.08 per cookie

Step-by-step explanation:

If you divide 1.28 (which is the total amount of butter) by 16 ( which is the amount of cookies that she made) you will get 0.08 ( which is the amount of butter in each cookie).

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
