Question

On number 9, you have to find the value of X. I attempted to solve the equation and got an answer of 46. Am I correct?

Answer 1

To solve this question, use proportion.

Since the rate of miles per hour is constant:

$\frac{x}{4}=\frac{184}{16}$

To find x, multiply both sides of the equation by 4.

$\begin{gathered} \frac{x}{4}\cdot4=\frac{184}{16}\cdot4 \\ \frac{4}{4}x=\frac{184\cdot4}{16} \end{gathered}$

And, solve the multiplications and the division.

$\begin{gathered} 1x=\frac{736}{16} \\ x=46 \end{gathered}$

Answer: x = 46 miles.
