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
To find out is 3/20 is larger than 2 we will convert 3/20 to a decimal. Lets do it:-
3/20
3 ÷ 20 = 0.15
Is 0.15 larger than 2?
No, 0.15 is not larger than 2.
So, 3/20 isn't larger than 2.
Hope I helped ya!! xD
