X + y = 40
2.25x + 1.75y = 83.50
-1.75x - 1.75y = -70
2.25x + 1.75y = 83.50
.50x = 13.50

Answer:
1. Wind bounces and rolls sand along the ground, a process called saltation.
2. Sediment carried by the wind will drop to the ground when the wind's velocity decreases.
3. The force of the wind pushes particles up the windward slope of the dune as it moves.
4. The force of gravity allows particles to slide down the leeward slope of a dune as it moves.
Explanation:
Saltation is the process which involves the movement of the particles by the force of wind or water. The wind or the water removes the particles and carry them forward. Materials like pebbles and stones get carried away by the flow of water. The large particles get settled in the river bed.
