So sale price= normal price-dicount
sale price=100%-20%=80%
therfor
220=80%of origonal price
80%
percent means parts out of 100
80%=80/100=8/10
220=8/10of origonal price
multiply both sdies by 10
2200=8 of origoal price
divide by 8
2200/8=275
origonal price=275
2u^3v^4 is the greatest common factor of these monomials.
Hope this helps!

Pull out the common factor of 
:
Recall that 
:
Rationalize the denominator:
Given:
<span>43 students in his school liked skating and 21 of those students liked swimming, as well
</span><span>7 students who did not like skating but liked swimming
</span><span>6 students who liked neither skating nor swimming
Like skating Not like skating Total
Like swimming 21 7 28
Not like swimming 22 6 28
Total 43 13 56
All the bold numbers are the missing details. The regular numbers are the given numbers.
That is the table I came up with because the given choices are not understandable.
