Solve for z.
12 = 15(z-1/5

z=  1

Step-by-step explanation:

Rewrite the equation as  

15(z−1/5)z12

Apply the distributive property

15z+15(−1/5)=  12

Cancel the common factor of  5

15z+3*−1=  12

Multiply  3  by  −1

15z−3=  12

Divide each term by  15  and simplify

5z−1  =  4

Since the expression on each side of the equation has the same denominator, the numerators must be equal

5z−1=  4

Move all terms not containing  z  to the right side of the equation

5z=  5

Divide each term by  5  and simplify

z  =  1

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
