Answer:
2,070,281
Step-by-step explanation:
let x = number of years
let y = population
Given:
- initial population = 500000
- rate of increase = 7%
y = 500000 × 1.07^x
when x = 21:
y = 500000 × 1.07^(21) = 2070281.187... = 2,070,281

Step-by-step explanation:
Answer: 62
Step-by-step explanation: Set up your equation
- 21+x=2x-41 because the number (x) that 21 is added to is 41 <em>less than</em> (so subtraction) <em>twice </em>(so multiply the number x by 2) the number (x).
- Get the x's on one side by subtracting the single x
- 21=x-41
- Now add 41 to both sides to completely isolate x
- 62=x
- So, your answer is x=62. The number is 62.
Check your work. 62+21=83. 2(62)= 124. 124-41=83. Both equations equal 83, so the solution is correct.
