What is the value of z for the equation 1/3z = −5/6 + 1/6z?

a. 5
b. 2
c. −2
d. −5

1/3 z= -5/6+1/6 z

Simplify both sides of the equation

Subtract 1/6 z from both sides

1/3 z-1/6 z= 1/6z + -5/6-1/6 z

1/6 z = -5/6

Multiply both sides by 6

6*(1/6 z)=6*(-5/6)

z=-5

Answer : D

I hope that's help !

For part A, the majority of dots circled are what's called a cluster. The one point out by itself is called an outlier. As for part B, it seems that as the hours of computer games played go down, their test scores go up.

hope it helps.
