Answer: x=5, y=-5, z=6
Step-by-step explanation:
x+y+z=6 -> 2x+2y+2z=12
subtract 2x+4y+2z=2 from this, and you get -2y=10 -> y=-5
So, x+z=11 and -x-3z=-23
x+z=11
-x-3z=23
---------
-2z=-12
z=-6
Meaning x=5.
At (4,-4). Because, the first value is the horizontal x-coordinate and the second is the vertical y-coordinate, so the direction of going across the y-axis is a horizontal movement. Therefore, you must add 14 to the x-coordinate. You add because positive is the opposite direction of the your first x-coordinate, -10. So the answer is (4,-4).
Answer: 7 3/4
Step-by-step explanation:
From the question, we are informed that Steven has 10 1/4 pages of homework and that he finishes 2 1/2 pages every ten minutes.
The number of pages that Steven will have left after 10 minutes will be:
= 10 1/4 - 2 1/2
= 7 3/4
He'll have 7 3/4 pages left
