Nina can stitch of a dress in 4 hours. if d represents the number of dresses and h represents the number of hours, which equation represents this proportional relationship? a. d = 6h b. 3d = 4h c. d. d = 4h e.

D. d = 4h

Step-by-step explanation:

If Nina can stitch 1 dress (d) in 4 hrs (4h) the relationship would be written as d = 4h cuz the 1 dress takes 4hrs to stitch.

I hope that helps & that I explained well enough!

:)

the ansew  is 4h

i got it wrong and it said that was  correct

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
