Answer:
Step-by-step explanation:
Let x be the "number."
"twice the difference of a number and 16" can be written as:
2(x-16)
"is the same as three times a number less than 18" can be written as:
= 3(x<18)
I wonder if this was meant to say "is the same as three times a number less 18," instead of "less than 18." If so, we would have:
=3(x-18)
1. Using the sentence as written: 2(x-16) = 3(x<18)
2. Using the sentence as amended: 2(x-16) = =3(x-18)
Going with this interpretation:
2(x-16) = 3(x-18)
2x - 32 = 3x - 54
x = 22
Answer:
After 25 years the population will be:
- Australia: 22271200
- China: 1580220878
- Mexico: 157380127
- Zaire: 112794819
Step-by-step explanation:
Growth rate problem that has a growth rate proportional to the population size can be solved using the equation:
P(t) = P₀eʳᵗ
- t is your unit of time. It could be days, or hours, or minutes. It changes depending on each problem. In this problem, t is measured in years because you're jumping from 2000 to 2025. Years just makes the most sense to measure that leap in time.
- P(t) is the population at time t. An example in this problem could be P(20) would be the population 20 years after the initial count. or maybe P(12) would be the population 12 years after the initial count. or P(0) would be the initial count of the population.
- P₀ is the initial population at P(0)
- r is the growth rate.<u><em> Don't forget to convert the percentage to its decimal form</em></u>
Now that everything is set out, lets use the equation to solve for our answer.
P(t) = P₀eʳᵗ
