You mean 60%of 5 1/2? that makes more sense...
i would do it like this:

(60% is the same as

(so that there is no confusion, i've put it into an improper fraction
now we can multiply:





which is 3.3.
so 60% of 5 and a half is 3.3.
Answer: x = 6
Step-by-step explanation:
9(8 - x) = 3x
72 -9x = 3x
add 9x to both sides
72 = 12x
divide 72 by 12
x = 6
Well first subtract 29 - 5 = 24
Therefore, 24 + 5 = 29
And 29 - 24 = 5
In SOHCAHTOA you want to use cosine (CAH)
Cos75 = x/30
Use algebra to get x by itself.
So type into your calculator:
30cos(75) which equals 7.76
