$y\cdot \:2\frac{1}{2} =$ $2\frac{1}{2}=\frac{2\cdot 2+1}{2}=\frac{5}{2}$ $=\frac{5y}{2}$

a) $2y+\frac{1}{2}=\frac{4y+1}{2}$

b) $2y+\frac{1}{2}y=\frac{5y}{2}$

<h3><em>So b) is the expression that is equivallent.</em></h3><h3><em></em></h3><h3><em></em></h3><h3><em>Hope I helped you!</em></h3><h3><em>Success!</em></h3>

A 76 foot piece of rope is cut into three pieces where one piece is three times longer than the other two equal pieces. How long

jonny [76]

Let the length of one of the shorter pieces be $\ell$ . Then, we know that two of the pieces are that length, and the third piece is $3 \ell$ . Since these are all pieces of a rope, all we need to do to figure out the lengths is add all those together, solve for $\ell$ , and then plug that back in to the desired lengths:

$3 \ell + \ell + \ell = 76 ft.$
$5 \ell = 76 ft.$
$\ell = 15.2 ft.$

Shorter pieces: $\ell = \bf 15.2 ft.$
Longer piece: $3 \ell = \bf 45.6 ft.$
