Given that B is between A and C, find the indicated length.

AB = 21 and BC = 4.3. Find AC.

AC =

25.3

Step-by-step explanation:

Since B is between A and C, you can use parts-whole postulate to infer that AB+BC=AC.

And since AB and BC are given, substitute in their values, and solve.

21+4.3=25.3=AC

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
