3.7÷(1 2/9 −0.4) = 166.5/45 ÷ 37/45 = 4.5
0.4 = 40/100 = 2/5
2/5 = 18/45
1 2/9 = 11/9 = 55/45
55/45 - 18/45 = 37/45
3.7 = 370/100 = 18.5/5 = 166.5/45
ANSWER: 4.5
Answer:
46,400
Step-by-step explanation:
present population =40,000

Answer:
1.5 km/hour
Step-by-step explanation:
d is the David's speed in still water
c is the speed of the current
Going with the current, he travels d+c km per hour.
Going against the current, he travels d-c km per hour.
d+c = (20 km)/(2.5 hours) = 8 km/hour
d-c = (20 km)/(4 hours) = 5 km/hour
Add the equations to eliminate the c terms
d+c = 8
d-c = 5
----------
2d = 13
d = 6.5 km/hour
c = 8-d = 1.5 km/hour
