To solve, simply know that 1/5 of 20 is 4. How did you get that? You do 1/5x20. Which is 20/5. The answer is 4. Now multiply 4 by 4. 16. Now the left over 1/5 is 4. So, 4 is how many girls there are. (Make sure to label)

loris [4]

Answer:

H = h + x

h = 568 meters

Step-by-step explanation:

The helicopter descends 114 meters to be 454 meters above the ground.

Therefore, the equation which describes this situation using h as the original height will be given by

H = h + x ....... (1)

Where H is the final height from the ground and x is the height that the helicopter ascends(Positive sign) or descends(Negative sign). (Answer)

Here, in our case, H = 454 meters and x = -114 meters.

Therefore, the original height of the helicopter from ground will be

h = H - x = 454 - (-114) = 568 meters. (Answer)
