-(1)x + 5 = 10
-5 -5
----------------
-x = 5
+1 +1
----------
x = 6
4x + 9 - (10/(3x)) I favored the x^2 then expanded and simplified each rational term
To answer this question we will have to understand the nature of 
.
can be rewritten as: 
. Now, 
is an irrational number and thus any of the four operations of addition, multiplication, subtraction or division placed anywhere between any of these terms will always result in an irrational number.
The only way irrational numbers can be made rational is by dividing or multiplying the given irrational number by the same irrational number.
So 70.52 and 13.27
so 13.27 is what percent of 70.52
percent means parts out of 100
what percent of 70.52
'of' can be tranlated to mutiply
13.27=x% times 70.52
13.27=x/100 times 70.52
13.27=70.52x/100
13.27=0.7052x
divide both side by 0.7052
18.82
the answer is 18.8%
the easy way is
to find percent assume 70.27=100
so x/100=
13.27/70.52 then multiply by 100=0.18817 multipliy 100
18.817=round 18.8%
answer is 18.8%
