HELP ASAP A deep sea diver down dives 81 ft. from the surface he then dives 14 ft. deeper. There's a helicopter monitoring the diver from 1,800 ft. above the surface of the sea. What is the distance between the helicopter and the diver

1705

you would see how far down the diver is. so 81+14

after that you would simply subtract 1800 from your previous total

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
