Answer:
x/7<-3
x<-21
Step-by-step explanation:
x/7<-3
multiply the seven to get rid of x denominator
x<-21
Answer:
- 3x² is a term in the numerator
- x + 1 is a common factor
- The denominator has 3 terms
Step-by-step explanation:
You can identify terms and count them before you start factoring. Doing so will identify 3x² as a term in the numerator, and will show you there are 3 terms in the denominator.
When you factor the expression, you get ...
![\dfrac{3x^2-3}{3x^2+2x-1}=\dfrac{3(x^2-1)}{(3x-1)(x+1)}=\dfrac{3(x-1)(x+1)}{(3x-1)(x+1)}](https://tex.z-dn.net/?f=%5Cdfrac%7B3x%5E2-3%7D%7B3x%5E2%2B2x-1%7D%3D%5Cdfrac%7B3%28x%5E2-1%29%7D%7B%283x-1%29%28x%2B1%29%7D%3D%5Cdfrac%7B3%28x-1%29%28x%2B1%29%7D%7B%283x-1%29%28x%2B1%29%7D)
This reveals a common factor of x+1.
So, the above three observations are true of this rational expression.
8x+6=54
-6 -6
8x=48
8x /8=48/8
x=6 the bracelets were $6 a piece
