You are baking cookies for your class. there are 23 total students in your class and you have baked 12 cookies. write and solve an equation to find the additional number x of cookies you need to bake in order to have 2 cookies for each student. write your equation so that the units on each side of the equation are cookies per student.

Your equation must look like the following:

(something) = 2 cookies/student.

12+x cookies           2 cookies
=
    23 students          1 student

Solve the following equation:       12+x          2
                                                         
                                                       23             1

Cross-multiplying:  (1)(12+x) = (2)(23) = 46

12+x = 46
      x  = 46-12=34

Must make 34 more cookies to ensure that every student receives 2 cookies.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
