What is the quotient? n+3/2n-6 divided by n+3/3n-9
Stolb23 [73]

First some rewriting:

\dfrac{n+3}{2n-6}\div\dfrac{n+3}{3n-9}=\dfrac{n+3}{2(n-3)}\div\dfrac{n+3}{3(n-3)}=\dfrac{\frac{n+3}{2(n-3)}}{\frac{n+3}{3(n-3)}}

We see that the numerators of both fractions (n+3) and a term in the denominators (n-3) will cancel:

\dfrac{n+3}{2(n-3)}\div\dfrac{n+3}{3(n-3)}=\dfrac{\frac12}{\frac13}

Then

\dfrac{\frac12}{\frac13}=\dfrac12\cdot\dfrac31=\dfrac32

The length of a rectangular picture frame is 2 inches longer than twice the width. If the perimeter of the frame is 34 inches, f
lyudmila [28]
The length, l, is 2 more than twice the width, w.
l= 2w+2 (2 more than twice w)
In a rectangle, we have two of the same lengths and two of the same widths.
2l+2w=34
Divide by 2 on each side.
l+w=17
We remember that l is 2w+2
Substituting that back in we get,
2w+2+w=17
3w+2=17
3w=15
w=5
We sub w back into l+w=17
l+5=17
l=12
The dimensions are 5 by 12 inches.
