Final answer:
To determine the number of billion people with access to safe drinking water, solve the equation p + 1.2 = 7.0 by subtracting 1.2 from both sides, giving p = 5.8. Thus, 5.8 billion people have access to safe drinking water, yet a significant global water crisis remains.
Step-by-step explanation:
To find p, the number of billion people who have access to safe drinking water, we need to solve the equation p + 1.2 = 7.0. We do this by isolating p on one side of the equation:
- Subtract 1.2 from both sides of the equation:
- p + 1.2 - 1.2 = 7.0 - 1.2
- Simplify both sides:
- p = 5.8
Therefore, approximately 5.8 billion people have access to safe drinking water.
Despite these numbers, the global water crisis persists, affecting billions of people who lack adequate safe drinking water and sanitation facilities. Urgent improvements are needed, especially in the developing world, to increase access to these essential resources.
