You are baking cookies for your class. there are 23 total students in your class and you have baked 12 cookies. write an equation to find the additional number of 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.

we are given

total number of students =23

the additional number of cookies =x

you have baked 12 cookies

so, total number of cookies =x+12

the additional number x of cookies you need to bake in order to have 2 cookies for each student

so, we can find total number of cookies

total number of cookies = ( total number of students)*(cookies each student)

so, we can plug values

total number of cookies = ( 23)*(2)

total number of cookies = 23*2

so, we can set them equal

x+12=23*2x+12=23∗2

we can divide both sides by 23

\frac{x+12}{23} =2

23

x+12

=2

so, the equation is :

\frac{x+12}{23} =2

23

x+12

=2

now, we can solve for x

Subtract both sides by 12

x+12-12=46-12x+12−12=46−12

x=34x=34

so,

the additional number of cookies is 34 it

correct

step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
