A rectangle's width is twice as long as its length. If the perimeter is 36 in., what is the length?
Bumek [7]
Okay here: 

Let L be the length and W the width of the rectangle. 

1. w=2•L
2. 2L+2W=36

Substitute eq. 1 into eq. 2, 

2L+2•(2•L)=36

2L+4L=36

6L=36

L=9

Not done yet, then from eq. 1, 
 
W=2•L
W=2•9
W=18 <------- Your answer. :)

Iteru [2.4K]

The speed is the ratio between the distance and the time:

s=\frac{d}{t}

Data:

d=6343miles

t=9h

s=\frac{6343\text{miles}}{9h}=704.77\frac{miles}{h}Then, the plane traveled at a speed of 704.77 miles per hour.

3y - 5z = -23
leonid [27]
Starting off, we can multiply the third equation by 2 and add it to the third to get rid of both the x and y variables. Next, we get z=1. Plugging that into 3y-5z=-23, we get 3y-5=-23. Adding 5 to both sides, we get 3y=-18. After that, we can divide both sides by 3 to get y=-6. Plugging that into -2x-y-z=-3, we get -2x+6-1=-3=-2x+5. Subtracting 5x from both sides, we get -2x=-8. After that, we can divide both sides by -2 to get x=4.
