because it halves: 4 ----> 2 so the result also halves ( 1004:2=502 and 100:2=50 )

A plane traveled 2565 miles with the wind in 4.5 hours and 2205 miles against the wind in the same amount of time. Find the spee
kherson [118]

Answer:

  • plane: 530 mi/h
  • wind: 40 mi/h

Step-by-step explanation:

Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...

  speed = distance/time

  p +w = (2565 mi)/(4.5 h) = 570 mi/h

  p -w = (2205 mi)/(4.5 h) = 490 mi/h

Adding these speeds, we get ...

  (p +w) +(p -w) = (570) +(490) mi/h

  2p = 1060 mi/h

  p = 530 mi/h

Then the speed of the wind is ...

  w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h

The plane's speed is 530 mi/h; the wind speed is 40 mi/h.

Solve the system of equations x - 2y = – 7 and -3x – 2y = 29 by combining the<br> equations.
Ksivusya [100]

Answer:

x = - 9, y = -1

Step-by-step explanation:

<em>Given:</em>

<em />\begin{bmatrix}x-2y=-7\\ -3x-2y=29\end{bmatrix}

Solve:

\mathrm{Substitute\:}x=-7+2y

\begin{bmatrix}-3\left(-7+2y\right)-2y=29\end{bmatrix}

\begin{bmatrix}21-8y=29\end{bmatrix}

\mathrm{For\:}x=-7+2y

\mathrm{Substitute\:}y=-1

x=-7+2\left(-1\right)

x=-9

\mathrm{Thus, Answer:x=-9,\:y=-1}
