I think if you opened one door you could see the backside of all of the others to determine if this was true or not.
'x' = number of postcards
sends off 5 now has x-5 remaining
sends off 1/2 now has 1/2 (x-5) remaining
thens sends one to sis 1/2 (x-5) -1 remaining and this equal 4
1/2 (x-5) -1 = 4 solve for 'x' the number of postcards he purchased....
You are correct.....I used 2004 instead of 2014 yikes ! Thanx...I fixed it !
1 is to 100 000 as 'x' is to 44 700
1/100 000 = x / 44700
44 700 / 100 000 = x ft Then convert your answer to inches by multiplying by 12 in/ft
WHERE is this mountain????
See this answer and you SHOULD be able to figure thisone out:

The model is the smaller number (it's a model after all)
Make sure that your dimensions are all in cm model 6cm car 300cm
car : model
300 : 6 which simplifies to 50: 1
It increased 14 years from 2000 - 01 01-02 02-03 and 03-04 etc ...
220.9 (r)^n = 262.5
r^14 = 262.5/220.9
r^14 = 1.188320507 solve for r
Exterior angles of a polygon sum up to 360 degrees
360/20 = n
180 guests / 10 guests/recipe = 18 recipes
18 recipes x 1.8 kg/recipe = 32.4 kg
32.4 kg x 2.2 lb/kg = 71.28 pounds of eggplant
H = .75 K
H+30 = .8 (1.25K) since H = .75K substitute this in
.75K + 30 = .8(1.25K)
.75K + 30 = K
.25K = 30
K = 120 then H = .75K = 90 YOU should check these answers.....are they correct? WHat do YOU think?
If you add 25 to H does it equal 80% of 1.25 K ?
