Answer:

The number of years that will the two villages have the same number of residents is 61 years

Step-by-step explanation:

Let's assume number of years as 'x'

First Pond:

Fresh pond has a population of 854

and it’s increasing by 3 people per year

so, we can find equation for population of first pound

[tex]P=854+3x[/tex]

Second pond:

Strawberry has a population of 427

and it’s increasing by 10 people per year

so, we can find equation for population of first pound

[tex]P=427+10x[/tex]

Since, populations are equal

so, we can set both equation equal and then we can solve for x

[tex]P=427+10x=854+3x[/tex]

[tex]427+10x=854+3x[/tex]

[tex]7x=427[/tex]

[tex]x=61[/tex]

So,

The number of years that will the two villages have the same number of residents is 61 years
