In the following exercise, solve each equation using the Division and Multiplication Properties of Equality and check the solution.
$鈭� \frac{7}{20} = 鈭� \frac{7}{4} v$

Short Answer

Expert verified

On solving, we get $v = \frac{1}{5} .$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenequationis 鈭� \frac{7}{20} = 鈭� \frac{7}{4} v . \\ Wehavetosolvethegivenequationandthenverifytheresult. \end{array}$

Step 2. Simplify

$\begin{array}{l} Now, \\ 鈬� 鈭� \frac{7}{20} = 鈭� \frac{7}{4} v \\ 鈬� 鈭� \frac{4}{7} 脳 (鈭� \frac{7}{20}) = 鈭� \frac{7}{4} 脳 (鈭� \frac{4}{7} v) [Multiplybothsidesbyreciprocalof 鈭� \frac{4}{7}] \\ 鈬� 鈭� \frac{4}{7} 脳 (鈭� \frac{7}{4 脳 5}) = v \\ 鈬� \frac{1}{5} = v \\ o r \\ 鈬� v = \frac{1}{5} \end{array}$

Step 3. Checking the result

$\begin{array}{l} Wehave, \\ 鈬� 鈭� \frac{7}{20} = 鈭� \frac{7}{4} v \\ 鈬� 鈭� \frac{7}{20} = 鈭� \frac{7}{4} (\frac{1}{5}) [Substitute v = \frac{1}{5}] \\ 鈬� 鈭� \frac{7}{20} = 鈭� \frac{7}{20} \\ L.H.S = R.H.S \\ Henceverified. \end{array}$
