Reduce 35/100 to 7/20 by dividing both sides by 5.
2/5 is bigger than 7/20.
2/5 > 7/20 or 2/5 > 35/100 if you leave it unsimplified
Hope this helps :)
Answer: After 7 years the population will be one-half the initial amount.
Step-by-step explanation:
Given: Initial population = 500,000
The population declines according to the equation:
, where P is the population in t years later.
One-half the initial amount = 0.5 x 500,000
= 250,000
Put P(t)=250,000, we get

Hence, After 7 years the population will be one-half the initial amount.
The answer is $7.14!
All you have to do is subtract 10 by 2.86.
The factor that multiplies with 6 to get 18 is 3 but the factor that multiplies with 6 to get 30 is 5.
The numbers in parenthesis should be a 5 and not a 10.
18 + 30 = 6(3 + 5)
