DId you see that I said that there is no number for this becuase that is what I mean
solution(1)
so we have 17-3+9-3=14+6=20 so 30 people own a cat or a dog
solution(2)
there is 17+9-3=23 people we then do 23-3=20 people who own a cat or a dog
so we have 24*1/3+24*1/4+24*1/8=8+6+3=17 hours so he has 24-17=7 hours left
since it is 3/12 and 10/21 we find the common denominator to get 63/252 and 120/252 we find that it os (120-63)/252=57/252=19/84 so we get 19/84 as the final answer
4,5,6,7 because it has to be greater than 3 and less than 8
if it was positive then -sqrt2 would work but there is no number for this
3. (16sqrt3)/3
Since triangle RQT is isosceles, we have\(ST = QT - QS = QR - QS = 8 - 2 = 6.\)
4.
216+72sqrt3
there are 22, $1 bills since we get the equation x+2(x+11)+3(x-18)=100 where x=22 there so there are 22, $1 bills
s\o we have 65-60=5 and 60*10=600 then we do 600/5=120 which means 2 hours later at 5:10
Hint
we get 180-3angle A=AngleB
and
AB=BC-2
