<em>Answer:</em>

<em>Step-by-step explanation:</em>

<em>Rewrite the equation as </em> $\sqrt{x} 6a+r/5r$ <em> = m</em>

<em>Remove the radical on the left side of the equation by squaring both sides of the equation.</em>

<em>Then, you simplify each of the equation. </em>

<em>Rewrite: (</em> $\sqrt{\frac{6a+r}{5r} )^{2}$ <em> as </em> $\frac{6a+r}{5r} = m^{2}$ <em />

<em>Remove any parentheses if needed.</em>

<em>Solve for r. </em>

<em>Multiply each term by r and simplify."</em>

<em>Multiply both sides of the equation by 5.</em>

<em>Remove parentheses.</em>

<em>Subtract 5m^2)r from both sides of the equation.</em>

<em>Subtract 6a from both sides of the equation.</em>

<em>Factor r out of r-5m^2)r </em>

Divide each term by 1-5m^2 and simplify.

r = - $\frac{6a}{1-5m^2}$

There you go, hope this helps!

jake can carry 6 1/4 pounds of wood in from the barn. His father can carry 1 5/7 times as much as Jake. How many pounds can Jake

Studentka2010 [4]

It would be: 6 1/4 * 1 5/7
= 25/4 * 12/7
= 300/28 = 150/14 = 75/7

In short, Your Answer would be 75/7 or 10 5/7 Pounds

Hope this helps!
