over the next 30 years,some estimates place the worlds population going from roughly 7.2 billion people in the world to 10 billi

on in 2050. Currently, global food consumption equals around 3000 kilo-calories per person, per day and as global prosperity increases that number is expected to rise to roughly 3500 kilocalories person per day. Counting no other costs other than the cost of production (and this means costs to transport,land use costs, CO2 production,water use,ect), lets say it costs us 1 pollution unit to produce 1000 kilo-calories of food today. What is the current impact in pollution units per day to feed the planet?

Answer:

Current impact in pollution units per day=21.6 billion pollution units per day

Step-by-step explanation:

1 person consumes 3000 kilo-calories per person

Current population=7.2 billion people

Total calories the entire population produces=(7.2 billion×3000)

1000 kilo-calories causes= 1 pollution unit

To get the impact of the entire population=(7.2 billion×3000)/1000=21.6 billion pollution units per day

a system of two linear equations has infinitely many solutions. one of the equations in the system is y-3x=-3.write an equation
Troyanec [42]
The other equation could be 

2y - 6x = -6

Solving:-

y - 3x = -3..........(1)
2y - 6x = -6........(2)
multiplyng the first equation by 2 gives
2y - 6x = -6

so equations (1) and (2) are the same equation
If we graph them they will be the same line 
Every point on that line will be a solution.

So there are infinitely many solutions

31+8=39

So, next will be:

39+8=47

47+8=55
