If I had 100 cookies and I gave my friend 40, and then I hate ten more, how many cookies would I have left?

You would have 50 cookies left

Step-by-step explanation:

You start out with 100 cookies and give 40 to a friend. At that point you have 60. After you eat 10 more, you should have 50 left. Hopefully they are some good cookies!

the answer is b.)

< 1=< 2

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
