How do I find the ratio?
Len [333]
You got it correct!
To get from 52 to 13, you divide by 4. And Vis versa, to get from 13 to 52, you multiply by 4. Considering they don't tell you which is the original, the only answer that is either 4 or 1/4 is F

Hope this helps!

Solve for x.
olga nikolaevna [1]

Answer:

\boxed{x=5},x=-9

Step-by-step explanation:

To rid the denominators, multiply both sides by (x-3)(x+1).

We get:

6(x+1)-12(x-3)=(x-3)(x+1)

Simplifying, we have:

6x+6-12x+36=x^2-3x+x-3,\\-6x+42=x^2-2x-3,\\x^2+4x-45=0

Solving, we get:

x^2+4x-45=0,\\(x-5)(x+9)=0,\\x=5,x=-9

Therefore, the solution with the greatest value is x=\boxed{5}

The perimeter of a rectangle swimming pool is 160 feet. The length of the swimming pool is four times its width . Find the dimen
Helga [31]
Formula for Perimeter of Rectangle:

P = 2(L + W)

Plug in 160:

160 = 2(L + W)

L = 4W
<span>So we can plug in '4W' for 'L' in the first equation.</span>
<span>160 = 2(L + W)

160 = 2(4W + W)

Combine like terms:

160 = 2(5W)

160 = 10W

Divide 10 to both sides:

W = 16

Now we can plug this back into any of the two equations to find the length.

L = 4W

L = 4(16)

L = 64

So the width is 16, and the length is 64.</span>
