Answer to Problem 43E

The width of the American flag is $5$ ft.

Explanation of Solution

Given:

Length of an American flag is $1.9$ times its width.

Formula Used:

The division property of equality states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal.

Calculation:

Given:

Length of an American flag is $1.9$ times its width.

Length $=9.5$ ft

Let the width be $x$ .

Thus, length $=$$1.9x$

Thus, the equation is:

  $1.9x=9.5$

Solving the above equation by applying Division property, we have:

  $\begin{array}{l}\frac{1.9x}{1.9}=\frac{9.5}{1.9}\\ x=5\end{array}$

Thus, the solution is $x=5$ .

Thus, the width of the American flag is $5$ ft.

Conclusion:

Hence, the width of the American flag is $5$ ft.
