Answer:
ab=bc because b devide ac in two equal sizes 
ac=ab+bc 
ac=2×ab 
ac =2×bc 
lets substitute ac and bc there we are given 
x+3=2(3x-1)
x+3=6x-2
-5x/-5=-5/-5
x=1
ab=3(1)-1
ab=2

Answer:
   6.0 miles
Step-by-step explanation:
The sequence of distances is a geometric sequence with first term a1 and common ratio (1 +10%) = 1.10. The sum of 7 terms of the sequence is ...
   S7 = a1·(r^7 -1)/(r -1)
   56.923 = a1·(1.1^7 -1)/(1.1 -1)
   5.6923 = a1·0.9487171
Dividing by the coefficient of a1 gives its value:
   5.6923/0.9487171 ≈ 5.999997 ≈ 6.000
The hiker traveled 6.0 miles on the first day.
 
        
             
        
        
        
The answer is y= -3x-3
