So multiply 128 by 15 to get 1920 and then move the decimal over two places to get 19.20 and then subtract that $19.20 from $128 to get $108.8
The correct answer would be 128.
Is this math cause I'm tryna figure it out
First you would simplify the left side to get,
ln( ( 3x+1 ) / ( 5+x ) ) = ln 2
Then raise both sides as the power of e, so it would basically cancel out the ln's.
3x+1 / 5+x = 2
3x+1 = 2( 5+x )
3x+1 = 10+2x
x = 9
We need the full picture, you cut off the bottom part which is the most important part..
