Imagine 20 more evenly-spaced frames—for a total of 30. Where should the new hooks go? Enter the values one by one into the middle column of the table, or enter an equation for d in terms of n that gives all the distances at once. When you finish, press "Submit." (d represents distance, n represents hook number.)​

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

t= 1/3.

hope this .
