Answer:
yes it is because 9 times 5 is 45 plus 9 is 54 and 54 is greater than 5
Let the two numbers be x and y
x + y = 18 . . . . . . . . (1)
x/y = 17 . . . . . . . . (2)
from (2): x = 17y
substituting for x in (1), gives
17y + y = 18
18y = 18
y = 18/18 = 1
x = 17y = 17(1) = 17
Therefore the two numbers are: 1 and 17
First, convert 1 kg to g.
1 kg = 1000 g
So 1000 g = 1.28
Set up a proportion:
1000/1.28 = 250/x
Cross multiply:
1000x = 320
Divide 1000 to both sides:
x = 0.32
So 250g costs £0.32
1 year = 365 days.
1 day = 24 hours.
1 hour = 60 minutes.
First convert the hours and minutes in Jupiter orbit to days:
14*60 = 840 +9 = 849 minutes.
849 / 60 = 14.15 hours.
14.15 / 24 = 0.59 days.
Jupiter's orbit is 4332.59 days.
Now divide that by 365 for the number of years:
4332.59 / 365 = 11.87 years.
