Which of these is a simplified form of the equation 7y + 8 = 9 + 3y + 2y?
7y = 6
2y = 1
12y = 17
5y = 17

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

5

step-by-step explanation:

(a) the volume of the cone is 20/3 in3
