Answer:
The 6x6 cube is 1/4 the area of the 12x12 cube.
100%=$1,636,364 (Rounded to the dollar)
Step-by-step explanation:
6x6=36
12x12=144
36/144=1/4

20%=?
25%=?
Remainder (55%=$900,000) so:
100%=$900,000/.55
100%=$1,636,364
All you have to do is multiply your number and then add them together !!
Number of Kian´s stamps=57+12x
number of Kai´s stamps=80+8x
x=number of months.
the number of Kian´s stamps must be the same than number of Kai´s stamps, so:
57+12x=80+8x
12x-8x=80-57
4x=23
x=23/4=5.75
The number obtained is decimal, therefore, they never will have the same number of stamps.
After 6 month, they will have almost similar numbers of stamps , but they never will have the same number of stamps.
Answer:they never will have the same number of stamps.
2x + 9 = 8
Subtract 9 from each side :
2x = -1
Divide each side by 2 :
x = - 1/2
