we know that
Using the original score as the basis
If Misha increased her test score from 
% to 
%
then
the increase variation is equal to
%-%=
%
to find the approximate percent increase of Misha's test score we apply a rule of three
if %--------------> represents 
%
%----------------->x
%
therefore
the answer is
the approximate percent increase of Misha's test score is 
%
So, to factorise something you are taking out the highest common factor.Here, 10 is an example of the highest common factor (I’ll refer to this as HCF)
10(2k+5)
Everything inside the brakets is multiplied by what’s directly next to it (if there is a negative sign, then that is included). So, 10 x 2k = 20k and 10 x 5 = 50
10(2k + 5) is the factorised version of 20k + 50
If the circumference of a pizza is 81 inches, the radius would be <em>12.89155 </em>inches.
Allison has 20 football cards, and 20 times 5 is 100. So 20+100=120.
She has 100 baseball cards
