A biologist collected 230 fern and moss samples. There were 110 fewer ferns than moss samples. How many fern samples did the biologist collect?

The biologist collected 60 fern samples.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of fern samples collected

y is the number of moss samples collected

A biologist collected 230 fern and moss samples.

This means that

There were 110 fewer ferns than moss samples.

This means that

How many fern samples did the biologist collect?

we want to find x

From the second equation

Replacing in the first equation

The biologist collected 60 fern samples.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
