Answer:
± 2
Step-by-step explanation:
let the number be n , then
n² - 4 = 0 ( add 4 to both sides )
n² = 4 ( take square root of both sides )
n = ± 
= ± 2
The number is - 2 or 2
Answer & Step-by-step explanation:
So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857, which is the answer. To double check, you'd just find 14% of 2285.7142857 (multiply by 0.14) which is equal to 320. Because you can't have fractions of people, however, you'd have to round the answer up to 2286 people.
If that is too difficult to understand them hope this is easier
14% of the towns population is 320. Let P denote the towns population.
14/100 * P =320
14P/100 = 320
14P = 32000
divide both sides by 14
P = 2285.71
the towns population is 2286
Hope this helps!
