Question

AX = 5, XB = 4, AC = 6, find AB.

24/5
10/3
15/2

Answer 1

AB= 15/2

Explanation:

got it right on odyssey :)

Answer 2

AX : XB as AB : AC
AX = 5
XB = 4
AC = 6
AB = x

5 : 4 as to x : 6
ratios can also be written as fractions...
5/4 = x/6 ..now we have a proportion...so we cross multiply
(4)(x) = (5)(6)
4x = 30
x = 30/4
x = 15/2 <==== AB = 15/2
