Answer:
x=3, y=1. (3, 1)
Step-by-step explanation:
6x+2y=20
0.5x-0.5y=1
-----------------
6x+2y=20
1/2x-1/2y=1
----------------
6x+2y=20
2(1/2x-1/2y)=2(1)
------------------------
6x+2y=20
x-y=2
-------------------
6x+2y=20
x=y+2
---------------
6(y+2)+2y=20
6y+12+2y=20
8y+12=20
8y=20-12
8y=8
y=8/8
y=1
x=1+2=3
x=3, y=1.
Answer:
<h2>
100, -50, 25, -12.5, 6.25, -3.125, 1.5625, -0.78125</h2>
Step-by-step explanation:
Each term is being multiplied by <u>-0.5</u>
How did I know?
Divide the second term by the first.
-50 divided by 100 = -1/2
Find the last four terms.
-12.5 x -1/2 =<em> </em><u><em>6.25</em></u>
6.25 x -1/2 = <u><em>-3.125</em></u>
-3.125 x -1/2 = <u>1.5625</u>
1.5625 x -1/2 =<em><u> -0.78125</u></em>
