## Answers ( )

Answer:Step-by-step explanation:A= 5/6 , B = 2/3, C = 9/6B (A + C) + C (A + B) I expanded the terms

AB + BC + AC +BC collect the two BC terms

AB + 2BC + AC

A==

5/6, B2/3, C =9/6AB + 2BC + AC substiutite the values in for the variables into the eq

(

5/6)(2/3) + 2(2/3)(9/6) + (5/6)(9/6)(10/18) + 2 (18/18) + 45/36

(10/18) + 2 (1) + 45/36

20/36 + 72/36 + 45/36 2 = 72/36

(20 + 72 + 45) / 36

137/36 This answer seems odd but I think it is corrector 3 29/36b)

divide15km by2hours to get the speed in _________ km/hr
