Segment addition postulate. Trying to help my son figure out how to solve. Given AC=39. A=2x-8, B=x×17. Find X, AB AND BC. We go
t 25 for X, and 42 for both AB, BC. Its not correct. 42+42 does not equal 39.

Segment addition postulate says
AB+BC=AC
assuming that A, B, C are in order, and assuming that those are the points,
legnth of AC=|A-C|=39 (|x| means absolute value of x)
A=2x-8
b=17x
AB=|A-B|=|2x-8-17x|=|-8-15x|
we are only given AB but not BC so this is not solvable unless you know BC
AB+BC=AC
BC=AC-AB
BC=39-|-8-15x|
that's as far as I can go since we don't know any more

Sam scored 98,25,105,62 and 65 run in 5 matches what was the average score per match
Jet001 [13]
To get the average you need to add all the numbers together and divide by the match number. So, 98+25+105+62+65=355. 355/5=71, therefore the average is 71
