Lucy baked 12 cookies. She baked 6 more and split them up equally between herself and 2 friends. How many cookies did each person have? Which equation represents the problem?

(12+6)÷3=x represents this problem.

Each person had 6 cookies.

Step-by-step explanation:

Lucy baked 12 cookies and then baked 6 more, which means the total number of cookies she baked is equal to 12+6.

Total number of cookies = 12+6

She then split them up equally between herself and her two friends, which means Lucy divided the (12+6) cookies among 3 people.

Let x be equal to the number of cookies each person had.

(12+6) cookies ÷ 3 people = the number of cookies each person had

(12+6)÷3=x

Therefore, the equation that represents this problem is (12+6)÷3=x.

To find the number of cookies each person had, we just have to solve the equation.

(12+6)÷3=x

18÷3=x

6=x

Therefore, each person had 6 cookies.

I hope this helps! Happy holidays :)

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
