To answer this we need to divide 12,000 by 10 and our answer will be the tenth of 12,000. Then we will check our work. Lets do it:-
12,000 ÷ 10 = 1,200
1,200 is the tenth of 12,000.
CHECK OUR WORK:-
1,200 × 10 = 12,000
We were RIGHT!!
So, 1,200 is the tenth of 12,000.
Hope I helped ya!!

Answer:
Step-by-step explanation:
y=-2x-4
y=5x+5
------------
-2x-4=5x+5
-2x-5x-4=5
-7x-4=5
-7x=5+4
-7x=9
x=9/-7
x=-9/7
y=5(-9/7)+5
y=-45/7+35/7
y=-10/7
Answer: x=-9/7, y=-10/7. (-9/7, -10/7).
----------------------------------------------------
-3x+y=8
2y=6x-10
----------------
6x-2y=10
-3x+y=8
-------------
y=8-(-3x)=8+3x
6x-2(8+3x)=10
6x-16-6x=10
-16=10
no solution
Answer: No Solution
--------------------------------
2y=4(x+3)
y-2x=6
--------------
y=4x+12
y=2x+6
--------------
4x+12=2x+6
4x-2x+12=6
2x+12=6
2x=6-12
2x=-6
x=-6/2
x=-3
y=2(-3)+6=-6+6=0
Answer: x=-3, y=0. (-3, 0).
-------------------------------------
x+2y=4
4x-2y=16
---------------
5x=20
x=20/5
x=4
4+2y=4
2y=4-4
2y=0
y=0/2
y=0
Answer: x=4, y=0. (4, 0).
