Purple marbles = P
Red marbles = R
Equations
P + R = 114
P = 5*R + 6
Solution
Put the second equation into the first.
5*R + 6 + R = 114 Combine like terms on the left
6R + 6 = 114 Subtract 6 from both sides.
6R +6-6 = 114-6 Combine
6R = 108 Divide by 6
6R/6 = 108/6
R = 18
=======================
P+R = 114
P + 18 = 104 Subtract 18 from both sides.
P + 18-18=104 -18 Do the subtraction
P = 86
Answer:
They store water in the ground. ... The Water RE-Cycle Water from Earth's surface evaporates into the air, condenses into clouds, and falls back to Earth again as precipitation (such as rain). Water can easily pick up that pollutant and carry it down into the groundwater or through the watershed to a lake or a river.
When water enters the watershed as rain or snow, it is called precipitation. Trees and plants use much of the precipitation and then release it back into the air as water vapor. ... This continuous movement of water from the air to a watershed and back to the air is called the water cycle.

Explanation:
Americans are more racially and ethnically diverse than in the past, and the U.S. is projected to be even more diverse in the coming decades.
Women’s role in the labor force and leadership positions has grown dramatically.
The world is aging. The demographic future for the U.S. and the world looks very different than the recent past. Growth from 1950 to 2010 was rapid — the global population nearly tripled, and the U.S. population doubled.
Christians are declining as a share of the U.S. population, and the number of U.S. adults who do not identify with any organized religion has grown.
The share of Americans who live in middle class households is shrinking
The American family is changing. After decades of declining marriage rates, the share of American adults who have never been married is at an historic high.
