Nikitich [7]

Answer:

Step-by-step explanation:

$A=\begin{bmatrix}0 &0 &5 \\ 0 &0 &-3 \\ 0 &0 &3 \end{bmatrix}$

$B=\begin{bmatrix}8 &-12 &5 \\ 7 &19 &5 \\ 0 &0 &0 \end{bmatrix}$

A.B = A × B

$A.B=\begin{bmatrix}0 &0 &0 \\ 0 &0 &0 \\ 0 &0 &0 \end{bmatrix}$

6-1/2z=2/3<br> what is z?

Marina CMI [18]

6 - 1/2z = 2/3
subtract 6 from both sides
- 1/2z = -16/3
divide both sides by -1
1/2z = 16/3
rewrite
1z/2 = 16/3
multiply both sides by 2
1z = 32/3
z = 32/3 or 10 2/3

Hope this helps :)

Use the distributive property.
(3/8)*(16x-24)=(3/8)(16x)-(3/8)(24)
16x*3/8=48x/8=6x
24*3/8=72/8=9
6x+9

Hope this helps!
