1 answer:

6 0

I'm a bit confused about way to write this equation down, so I will solve this both ways, and you will chose whitch you had in mind ;)

$\frac{v+9}{3}=8$
$v+9=8*3$
$v=24-9$
$v=15$

or:

$v+\frac{9}{3}=8$
$v+3=8$
$v=8-3$
$v=5$

Big town is 5.121 times larger than Small town.

Step-by-step explanation:

Step 1:

In order to determine how much larger Big town's population is to Small town's population is, we need to convert the exponentials into actual numbers.

Small town's population $= 4.10\times 10^{4} = 41,000.$

Big town's population $= 2.10\times 10^{5} = 210,000.$

Step 2:

In order to determine how much larger Big town's population is to Small town's population is, we divide Big town's population by Small town's population.

$\frac{210,000}{41,000} = 5.121.$
