The answer is 100,000
<span>In order to answer this, you must got to the number in the hundred thousand spot, in this case 1, and the check the number next to it. If it is 5 or more, the number becomes bigger, and if it is less than 5, you keep the number the same. After this, any numbers to the right become zeros. </span>
Answer:2 1/2 divided by 5/8 = ?
Step-by-step explanation:
I:2x – y + z = 7
II:x + 2y – 5z = -1
III:x – y = 6
you can first use III and substitute x or y to eliminate it in I and II (in this case x):
III: x=6+y
-> substitute x in I and II:
I': 2*(6+y)-y+z=7
12+2y-y+z=7
y+z=-5
II':(6+y)+2y-5z=-1
3y+6-5z=-1
3y-5z=-7
then you can subtract II' from 3*I' to eliminate y:
3*I'=3y+3z=-15
3*I'-II':
3y+3z-(3y-5z)=-15-(-7)
8z=-8
z=-1
insert z in II' to calculate y:
3y-5z=-7
3y+5=-7
3y=-12
y=-4
insert y into III to calculate x:
x-(-4)=6
x+4=6
x=2
so the solution is
x=2
y=-4
z=-1
Answer:
Step-by-step explanation:
This equation can simply be solved by adding 15 to both sides.
