3(6x-8)-(-4x-7)
18x-24+4x+7
ANSWER= 22x-17
You do 28/100 which is 0.28
You then multiply this by 21
28/100 x 21 = 5.88
Here is what your answer should of looked like. :)
5x + 10 10
---------- = -------
121 11
make the bottom have same common denominator
10/11 x (10/10) = 100/121
Get rid of the denominator (for both now have 121 as a base)
5x + 10 = 100
5x + 10 (-10) = 100 (-10)
5x = 90
5x/5 = 90/5
x = 18
x = 18 is your answer
hope this helps
