Hi I need help! Please answer! You will get brainlest! Walking at a steady pace, Ella walked 11 miles in 3 hours. Which mixed number shows how many miles she walked in a hour? It has to be correct! If it is wrong, then I will report you! A: 2/3
B: 2 2/3
C: 3
D: 3 2/3.

D

Step-by-step explanation:

because it is 3.666 and if you put it into a fraction it would be 3 2/3 duh

this doesn't make sense 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
