Answer:
360 screws
Step-by-step explanation:
First we need to determine how many screws she needs for the 2 decks
We will determine the number of screws for 1 deck
1 deck uses 25 pieces of wood
25 pieces of wood * 8 screws/ piece of wood = 200
200 screws per deck
She is building 2 decks
2 * 200 = 400
400 screws for the 2 decks
She has 40 screws
400 screws she needs - 40 screws she has = 360 screws she still needs
The correct answer is A.
In order to find the correct answer in this one, you have to group all of the like terms. In this case, each term is unique with the exception of the x^2y^3 terms. Therefore, we need to check those first.
4x^2y^3 - (-5x^2y^3)
4x^2y^3 + 5x^2y^3
9x^2y^3
Since this term is included, we look for answers that involve this one. A is the only one that does. Plus, it includes each other term unchanged (which is good since there are no other like terms). Therefore, A is your answer.
Answer:
(3/4y)
Step-by-step explanation:
it is the pattern!!!

180-40= 140
140/2= 70
X=70
