Answer:
Fraction of the original board left = 
Step-by-step explanation:
Let the length of the board is = l feet
Marty saws off 
of a wooden board.
Length of the board left = l - 
= 
feet
He saws off 
of the remaining board,
Board left = ![(\frac{4}{5})l-[(\frac{4}{5})l\times (\frac{3}{4})]](https://tex.z-dn.net/?f=%28%5Cfrac%7B4%7D%7B5%7D%29l-%5B%28%5Cfrac%7B4%7D%7B5%7D%29l%5Ctimes%20%28%5Cfrac%7B3%7D%7B4%7D%29%5D)
= 
= 
feet
He finally saws off 
rd of the remaining board.
Board left = ![\frac{1}{5}l-[\frac{1}{5}\times \frac{1}{3}]l](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7Dl-%5B%5Cfrac%7B1%7D%7B5%7D%5Ctimes%20%5Cfrac%7B1%7D%7B3%7D%5Dl)
= 
= 
feet
Fraction of the original board left = 
=
Answer:You answered 19 questions correctly and 1 question wrong
Step-by-step explanation:First you have to divide 20 by whatever number that can get you to the number 100 by 20,which is 5(100 divided by 5 equals 20)Lastly you have to divide 95 by 5 and you get 19!

Step-by-step explanation:
How do you factor trinomials? -
You factor trinomials by using methods like FOIL multiplication and simple factoring patterns.
How can we check the binomial factors to verify that they are truly factors?
We can multiply the binomial factors out to see that they are truly factors.
Create an example of a trinomial and factor it to its binomial factors.
+5x+6 factors into
(x+2)(x+3).
Sorry for the trashy answer.
Get n by itself in both inequalities
(This program doesn't allow for regular less than or greater than signs, so for the purposes of this problem I will be using less than or equal to (≤) and greater than or equal to (≥) signs)
Inequality 1:
Inequality 2:
Now that you have both of the n's by themselves, you can put the two inequalities together, like this
Just keep in mind that these are supposed to be regular less than signs
