\displaystyle \frac{4x+3}{5} ^{/9}=\frac{8x-1}{9}  ^{/5} \\\\\\ 36x+27=40x-5 \\\\ 40x-36x=27+5\\\\ 4x=32 \\\\ \boxed{x=8 }

Step-by-step explanation:

Given fractional expression:

(4x+3)/5 = (8x-1)/9

By doing cross multiplication, we get

⇛4x(9) + 3(9) = 8x(5) - 1(5)

⇛36x + 27 = 40x - 5

Now, combine the like terms in one side.

⇛27x - 40x = -5 + 36

⇛-13x = 31

⇛x = 31/-13 Ans.

Anon25 [30]

Answer: 2023

Step-by-step explanation:

Since, the initial population of the city is 55,210,

And, it is declining at a rate of 1.09%.

Thus, the function that shows the population after x years since 2010 is,

f(x) = 55210(1-\frac{1.09}{100} )^x

f(x) = 55210(1-0.0109)^x

f(x) = 55210(0.9891)^x

If the population of town is 48000 in x years.

⇒ 55210(0.9891)^x= 48000

⇒ (0.9891)^x= 0.869407715993

⇒ x = 12.769

Therefore, after 12.769 years the population of town will be equals to 48,000

⇒ After 12.770 years the population will first be below 48,000.

⇒ After approx 13 years the population will first below 48,000.

⇒ Around 2023 the population will be first below 48,000.
