Answer:
x = 4, RM = 7
Step-by-step explanation:
Given RM = x+3 and MS = 2x-1, if M is on between R and S, then RM = MS
x+3 = 2x-1
collect like terms;
x - 2x = -1-3
-x = -4
Divide both sides by -1
-x/-1 = -4/-1
x = 4
Since RM = x+3, substitute x = 4 into the expression to get the lrngth of Rm.
RM = 4+3
RM = 7
Hence x = 4, RM = 7
