Answer:
x=−21
Step-by-step explanation:
Pi * 5 squared = 25 Pi
25 Pi * 5 = 125 Pi or 392.6990817
and I'm not sure how to round to inch cube sorry. :(
2x+3y= -17
5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x.
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to:
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you:
-15y=85
4y= -8
You add them top numbers by the bottom and get:
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one.
5x + 2(-7) = -4
5x -14 = -4
5x = 10
x = 2
So the answer is (2,-7) or x=2 and y=-7
0.824.....Apex if answer changed not my fault but kinda helpful
Let the number be x.
6x-20=94
6x=114
x=19
