Let the cost of the dryer = x
let the cost of the washer = y

x + y = 750
y = 2x

Substitute: 

x + 2x = 750
3x = 750
x = 250

250 + y = 750
y = 500

Therefore, the cost of the washer is $500 and the cost of the dryer is $250! :)
I hope this helps you! :D

Solve 3(x - 2) &lt; 18. A{x\x&lt;8)<br> B{x1x &gt; 8)<br> C[xlx&lt;-8}<br> D{xl x&gt;-8)
Evgen [1.6K]

Answer:

A. {x | x < 8}

Step-by-step explanation:

First, we divide both sides by 3.

3(x - 2)/3 < 18/3

Then simplify.

x - 2 < 6

Lastly, add 2 to both sides.

x - 2 + 2 < 6 + 2

<u>x < 8</u>

Can someone help me with this question? You don’t really have to tell me the answer but just how to solve it.
Veronika [31]

part A

if the paperbacks are 40% less, that means 100% - 40% = 60%, they actually are 60% of the price of the hardcover ones.

\bf \begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{60\% of 24.99}}{\left( \cfrac{60}{100} \right)249.99}\implies 14.994

part B

so, if they return it, they get 1/3 credit, if they try to sell it, is half off, which is more than 1/3.  22 got damaged.

\bf \stackrel{\textit{damaged books at half-price}}{(22\cdot 14.994)\cfrac{1}{2}\implies 164.934}~\hfill \stackrel{\textit{damaged books at one-third price}}{(22\cdot 14.994)\cfrac{1}{3}\implies 109.956} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill 164.934 - 109.956 = 54.978~\hfill

part C

\bf \textit{First Day}~\hfill \stackrel{hardcover}{3(24.99)}+\stackrel{paperback}{8(14.994)}+\stackrel{damaged}{3\left( 14.994\cdot \frac{1}{2} \right)} \implies 217.413 \\\\\\ \textit{Second Day}~\hfill \stackrel{hardcover}{4(24.99)}+\stackrel{paperback}{5(14.994)}+\stackrel{damaged}{8\left( 14.994\cdot \frac{1}{2} \right)}\implies 234.906 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \boxed{17.493}

I don't think she is incorrect, $17.5 is close to $20, she didn't say it was exactly $20, just thereabouts, and 17.5 is around that much.
