<PRE><B>Question 1006580</B>
 a triangle has a perimeter of 23 m 
side B is twice as long as side A 
side C is 5 less than side A 
--------
what is the length of side C ? i know that x+2x+x-5=23 combine the x&#39;s and you get 4x-5=23 add 5 to both sides and you get 28 divide that by 4 and you get 7 from their it says find the length of side C using x-5=___m 
-----
Equations:
A + B + C = 23
B = 2A
C = A-5
---------------
A + 2A + A-5 = 23
4A = 28
A = 7
----
C = A-5 = 2
