D As asking everyone would impossible .but taking a random sample out of the crowd will be unbiased and bring a good percentage.
answer is 5 2/3.............
Answer:
Step-by-step explanation:
5)
DG= 60 (whole)
DO= 4x-3 (Part)
OG= 2x+ 21 (Part)
4x-3+ 2x+21= 60
6x+18=60
6x=42
x=7
Using this we can solve for DO and DG
DO= 4*7-3
DO= 25
DG= 2*7+21
DG= 14+ 21= 35
6)
TB is whole
TU is part
UB is part
5x= 4x-1+2x-1
5x=6x-2
x=2
UB= 2*2-1= 4-1= 3
TU= 4*2-1= 8-1= 7
6x+1(3x-12)=6
6x+3x-12=6
9x-12=6
+12= 18/9 x=2
Y=6-12
Y=-6 (2,-6
