To determine

To find: Evaluate each expression.

Answer to Problem 50CCR

  $-6z÷\left(-3y\right)=-3$

Explanation of Solution

Given information:

  $-6z÷\left(-3y\right)$

  $\begin{array}{l}y=-4\\ z=6\end{array}$

  $-6z÷\left(-3y\right)$

On substituting

  $\begin{array}{l}y=-4\\ z=6\end{array}$

On solving

We get

  $\begin{array}{l}-6z÷\left(-3y\right)=\frac{-6z}{-3y}\\ \Rightarrow -6z÷\left(-3y\right)=\frac{2z}{y}\\ \Rightarrow -6z÷\left(-3y\right)=\frac{2\left(6\right)}{-4}\\ \Rightarrow -6z÷\left(-3y\right)=\frac{12}{-4}\\ \Rightarrow -6z÷\left(-3y\right)=-3\end{array}$

Therefore,

  $-6z÷\left(-3y\right)=-3$
