Step-by-step explanation:

Answer:
AB = 8
Step-by-step explanation:
AC = 36
AB/BC = 2/7
AB = (2/7)BC
AB + BC = 36
(2/7)BC + BC = 36
(9/7)BC = 36
BC = 36(7/9)
BC = 4*7
BC = 28
AB + BC = 36
AB = 36 - 28
AB = 8
======
Is AB/BC = 2/7?
8/28 = 2/7 YES
200,000+10,000+8,000+300+70+5 is 218,375 in expanded form!!!
