Answer:
1,632(
Step-by-step explanation:
I did 34,284/252 to figure out the # of groups with 252 people
I got 136.04-- rounded it to 136
I then multiplied 136*12=1,632
so 1,632 people have type A blood
-2x + 16 < = 10
-2x < = 10 - 16
-2x < = - 6
x > = -6/-2
x > = 3............so any number that is 3 or above is in the solution set
X=12 because 73-3x=61-2x so add 3x to both to make 73=61+X then subtract 61 from both to get 12=X
