Answer:
1.8611 x 10^4 lbs per capita
Step-by-step explanation:
To calculate the per capita garbage we have to divide the amount of garbage by the number of people
garbage = 5.416 x 10^12 lbs
people = 2.91 x 10^8
5.416 x 10^12 / 2.91 x 10^8 =
To make it easier we can take the scientific notation of the first term to the same exponent the second
5.416 x 10^12 = 54,160 x 10^8
54,160 x 10^8 / 2.91 x 10^8 =
Now that we have multiplying the same in both parts of the division you can simplify both terms above and below
54,160/2.91 = 18,611
18,611 = 1.8611 x 10^4
Answer:
the answer is x^2+8x+ c
Step-by-step explanation:
If x

Answer:
//Solve equation [2] for the variable y
[2] y = 4
// Plug this in for variable y in equation [1]
[1] (4) - x = -2
[1] - x = -6
// Plug this in for variable y in equation [4]
[4] (4) - 2x = 1
[4] - 2x = -3
// Solve equation [1] for the variable x
[1] x = 6
// Plug this in for variable x in equation [3]
[3] (6) = 3
[3] 0 = -3 => NO solution
No solution
