Answer:

z=−3

Step-by-step explanation:

1/2*z+6-(3/2*(z+6))=0

Simplify 3/2

1                3

 ((— • z) +  6) -  (— • (z + 6))  = 0  

   2                2

     

Simplify   1/2

Rewrite the whole as 6.1     Pull out like factors :

  -2z - 6  =   -2 • (z + 3)  a fraction using  2  as the denominator.

-z - 3  = 0

7.1      Solve  :    -z-3 = 0  

Add  3  to both sides of the equation :  

                     -z = 3

Multiply both sides of the equation by (-1) :  z = -3

Answer:

z = -3

Step-by-step explanation:

\frac{1}{2}z+6 = \frac{3}{2}(z+6)

Expand and cancel out brackets.

\frac{1}{2}z+6 = \frac{3}{2}z +

Simplify.

\frac{1}{2}z+6 = \frac{3}{2}z + 9

Isolate x and numbers.

\frac{3}{2}z - \frac{1}{2}z = 6-9

Simplify.

\frac{2}{2}z = -3

z = -3

What does complumentary mean in geometry?
Bumek [7]
If you have a right triangle and one angle in the triangle is 45 degrees, the other would have to be complementary (an angle that adds up to another to form a right angle) so the other angle would have to be 45 degrees to make that a right angle 90 degrees. So complementary angles are two angles that add up to equal 90 degrees.
