Rachel has 30 pounds of a mixture of candy that sells for $1.00/lb. If lollipops sell for $0.95/lb and caramel candies sell for
dimulka [17.4K]
L = pounds of lollipop
c = pounds of caramel candies

0.95l + 1.10c = 30 ($0.95/lb & $1.10/lb)
l + c = 30 (mixture sells for $1/lb)
c = 30 - l

0.95l + 1.10(30 - l) = 30 (Substitution)
0.95l + 33 - 1.10l = 30
-0.15l = -3 (move terms)
l = 20lbs

Hope this helps.

\frac{2.75}{9} =\frac{x}{(2/9)}

To solve this proportion, cross multiply.

By cross multiplying, you will multiply 2.75 * (2/9) and 9 * x.

0.61 = 9x

Divide both sides by 9.

x = 0.067... which rounds to 0.068, so your answer is:

D) x \approx 0.068

The ratio of the length of a rectangular floor to its width is 3:2. If the length of the floor is 12 meters, what is the perimet
atroni [7]

Hi!

<h3>Let's set up a proportion and cross multiply to solve. </h3>

\frac{3}{2} \frac{12}{w}

<h3>Solve for w</h3>

2 * 12 = 24

24/3 = 8

<u>\frac{3}{2} \frac{12}{8}</u>

<h3>To find the perimeter of the floor, use this equation</h3>

<em>(l = length</em>

<em>w = width </em>

<em>p = perimeter)</em>

l + l + w + w = p

<u>12 + 12 + 8 + 8 = 40</u>

<h2>The perimeter of the floor is 40 meters. </h2>

Hope this helps! :)
