The problem is asking you to solve the equation
<em>y</em> = 12<em>x</em> + <em>n</em>
for the variable <em>n</em>. To do this, subtract 12<em>x</em> from both sides:
<em>y</em> - 12<em>x</em> = (12<em>x</em> + <em>n</em>) - 12<em>x</em>
<em>y</em> - 12<em>x</em> = <em>n</em>
Answer:
2 Miles Per Hour
Step-by-step explanation:
I get this answer by first converting hours to minutes. I got 180 minutes from 3 hours. I then divided 360/180 to get the miles per minute. This gave me 2 which was my Miles Per Minute.
29 minutes- at a rate of 1,000 feet a minute, it would take 32 minutes to reach sea level (32,000/1000=32)but if you subtract 3000 from 32000 to remain 3000 feet above sea level, you have 29000 feet to descend which will take 29 minutes

Step-by-step explanation:
Answer:
using the first two equations cancelling the z
-2x-2y-5z=-7
6x+8y+5z=9
4x +6y= 2
using the second and the third equations cancelling the z
6x+8y+5z= 9
-2x-3y-5z= -6
4x +5y = 3
4x + 6y = 2
-4x -5y = -3
y= -1
2x + 2(-1) + 5z = 7
2x - 2 + 5z = 7
2x + 5z = 9
6x + 8(-1) + 5z = 9
6x - 8 + 5z = 9
6x + 5z = 17
-2x - 5z= -9
4x = 8
x = 2
2(2) + 2(-1) + 5z= 7
4 - 2 + 5z = 7
2 + 5z = 7
5z = 5
z = 1
(2, -1, 1)
the answer is a.
