Answer:
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:
B. 6.5 ≤ x
Step-by-step explanation:
Nathan's pay for the week, including x extra hours, will be ...
250.25 +9.50x
We want that to be at least 312, so the inequality is ...
250.25 +9.50x ≥ 312
9.50x ≥ 61.75 . . . . . . . . subtract 250.25
x ≥ 6.5 . . . . . . . . . . . . . . divide by 9.5
The graph showing a solid dot at x=6.5 and an arrow extending to the right will be the correct graph of this solution.
