I think it would be no solution
4x-2(2x+8)=8
4x-4x+16=8
0x+16=8
16=8
which is wrong

Which example has the least percent error?
jeyben [28]
Sample 1:
Error = 14 - 13.7 = 0.3
Percentage Error = 0.3/13.7 x 100 = 2.19%

Sample 2:
Error = 24.4 - 24 = 0.4 
Percentage Error = 0.4/24.4 x 100 = 1.64%

Sample 3:
Error = 25.8 - 25 = 0.8
Percentage Error = 0.8/25.8 x 100 = 3.1%

Sample 4:
Error = 40.2 - 39 = 1.2
Percentage Error = 1.2/40.2 x 100 = 2.99%

Sample 2 has the least percent error

Help pls and no links
Svetlanka [38]

We know a or b != 0

but a-b==0 so both are the same unknown number

b/a must = 1

so

a/b is equivalent to b/a as a/b=1 as well.

So the last answer choice.
