The answer is B, divide the rate by the unit to simplify
Answer:
D) Multiply A by -4 and B by 5
Step-by-step explanation:
5x-2y=10
4x+3y=7
----------------
-4(5x-2y)=-4(10)
5(4x+3y)=5(7)
----------------------
-20x+8y=-40
20x+15y=35
---------------------
23y=-5
y=-5/23
5x-2(-5/23)=10
5x+10/23=10
5x=10-10/23
5x=230/23-10/23
5x=220/23
x=(220/23)/5
x=(220/23)(1/5)
x=220/115
x=44/23
Answer: The area is 
Step-by-step explanation:
The cross section AFGD is a rectangle. Then, its area can be calculated with this formula:
Where:
"A" is the area of the rectangle.
"l" is the lenght of the rectangle.
"w" is the width of the rectangle.
Then, from the figure, you can identify that the dimensions of the rectangle AFGD are:
Therefore, you can substitute these values into the formula to find the area of the cross section AFGD. Then, you get:
I think you forgot to give the diagram along with the question. I am answering the question based on my research and knowledge. "x = 7, y = 9" is the one among the following choices given in the question that gives the value of "x" and "y". The correct option among all the options that are given in the question is the third option or option "C".
