Answer:

C says 8x+12y, but D says 12x+8y, instead of 8x and 12y. The correct answer is C, I guess

Step-by-step explanation:

Let x=small rugs and y=medium rugs. It takes 8 hours to dye a small rug, so you would write 8x. It takes 12 hours to dye a small rug, so you would write 12y. Those two would need to be added together. The dyer needs to dye at least 22 rugs in 240 hours, so you would need a less than or = to sign.

I'm not sure which choice has the line beneath, indicating that the sign is a "less than or equal to" sign, but the answer is gonna be either C or D.

8x+12y≤240, or 12y+8x≤240

What price should a retailer place on an item that costs him $6.95, if he wants a markup of 33%? $
zubka84 [21]
So he wants to mark the product up by 33%, now, if we take 6.95 to be the 100%, what is 33% of that?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
6.95&100\\
x&33
\end{array}\implies \cfrac{6.95}{x}=\cfrac{100}{33}\implies \cfrac{6.95\cdot 33}{100}=x

so the marked up price will be 6.95 + x.

A picture inside a frame is 2 inches longer than it is wide. The picture is in a frame that has a width of 3 inches on each side
geniusboy [140]

Answer:

The dimensions of the frame are 15 in x 13 in

Step-by-step explanation:

Let

x ----> the length of the picture

y ----> the width of the picture

we know that

x=2+y -----> equation A

The area of the picture, including the frame is

A=(x+6)(y+6)

A=195\ in^2

so

195=(x+6)(y+6) ----> equation B

substitute equation A in equation B

195=(2+y+6)(y+6)

solve for y

195=(y+8)(y+6)\\y^2+6y+8y+48=195\\\\y^2+14y-147=0

solve the quadratic equation by graphing

The solution is y=7 in

see the attached figure

<em>Find the value of x</em>

x=2+7=9\ in

Find the dimensions of the frame

x+6=9+6=15\ in

y+6=7+6=13\ in

therefore

The dimensions of the frame are 15 in x 13 in
