I think n=4 is the answer
3 times.
If you use cross multiplication and using 2/3 and 2/1, you would get 6/2, which is equal to 3.
2x+8x=30. x= #of pens
10x=30. combine like terms
x=3. divide by 10 to isolate (get by itself) x
2(3)=6. the # of white pens are represented by 2x
6 white pens
hope this helped!
Answer:
D) 1
Step-by-step explanation:
using the distributive property we have ax+a+bx-b-2=0. because the equation is true for all real x, ax=-bx. this means a-b-2=0 and a=-b. a-b-2=0 becomes a=b+2. then we substitute a for -b and get -b=b+2 which becomes 2b=-2 so b=-1. since a=-b, a=1
