9(x + 3) + 15x
9x + 27 + 15x ...combine like terms
24x + 27 <==
I would say the best estimate would be 9 because the real answer is 8.71 and if you round that to the 1 place the answer would be 9.
2) longest line is (-1, -3) and (-1, 7)
3) (-1, -3), (-6,2), and (2,4)
1% of $32K is $320
5% of $32K is $1600
$1600 + $320 = 6%
TOTAL IS $1920
First, you divide the fraction, and then you multiply it by 100.
So you get:



So, 5/16 is 31.25%
Hope this Helps! :)
