Answer:
They have 714 stamps in all.
Step-by-step explanation:
Daniel has 102 stamps, and since Manuel has twice that, u multiply it two.
102 x 2 = 204.
Multiply THIS amount by two to get kendra's amount.
204 x 2 = 408.
Then, add 102, 204, and 408.
102 + 204 + 408 = 714
There are 714 total stamps.
Daniel has 102 stamps, so 102 is our first number.
Manuel has 2x as many stamps as Daniel (who has 102) so we do...
102 x 2 = 204
204 is our second number.
Kendra has 2x as many as Manuel (who has 204).
204 x 2 = 408
408 is our third number.
Now we add the three stamp numbers together to get the total:
AC = 2x - 13 Cm
BC = 3x + 4 Cm
AB = 36 Cm
AB = AC + BC
BC = AB - AC
= 36 - (2x - 13)
= 36 - 2x + 13
= 49 - 2x
but, BC = 3x + 4
so equating both the equation we get
3x + 4 = 49 - 2x
3x + 2x = 49 + 4
5x = 53
x = 53/5
x = 10.6
BC = 49- 10.6*2
= 49- 21.2
= 27.8 CM
it d probably think it's d
