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:

`(x)/(4)=(184)/(16)`

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

`\begin{gathered} (x)/(4)\cdot4=(184)/(16)\cdot4 \\ (4)/(4)x=(184\cdot4)/(16) \end{gathered}`

And, solve the multiplications and the division.

`\begin{gathered} 1x=(736)/(16) \\ x=46 \end{gathered}`

Answer: x = 46 miles.
