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:
Step-by-step explanation:
If our ratio is apple juice to orange juice, then the proportion will be
If we are looking for how much orange juice she needs if she uses 32 ounces of apple juice, then 32 goes on top of a new ratio and x goes on bottom:

x = 16 ounces of orange juice
If you fill in the last coordinates with the x and y you get (1,7)
