Question

Write a proportion for each statement. Then solve for the variable. A) the numbers -4.75 and 8 are proportional to the numbers -9.5 and k.

Answer 1

Given data:

The numbers -4.7 and 8 are proportional to the numbers -9.5 and k

So, we write it as

$\frac{-4.75}{8}=\frac{-9.5}{k}$$\begin{gathered} -4.75k=-9.5\times8 \\ k=\frac{-76}{-4.75} \\ k=16 \end{gathered}$

Thus, the value of k is 16.
