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.
<span>How to use base 10 blocks in
dividing 2.16 by 6
=> how many 6s are there in 2.16. Let’s try
let’s try the blocks of
=> 1 = IIIIIIIIIIIIIIIII = 17 6s (16.666..
* 6)
=> 2 = approximately 33 6s (33.33… * 6)
=> .16 = 0.27 6s or 3
=> 33 + 3 = 36 6s in 2.16
=> 2.16 / 6 = 0.36
Thus, there are 36 6s in 2.16 numbers. </span>
