Question

100POINTS! SHOW WORK OR I REPORT

Answer 1

• A-M-B

If M is the midpoint then then AM is AB/2

`\\ \sf\longmapsto (12x+40)/(2)=65`

`\\ \sf\longmapsto 12x+40=65(2)`

`\\ \sf\longmapsto 12x+40=130`

`\\ \sf\longmapsto 12x=130-40`

`\\ \sf\longmapsto 12x=90`

`\\ \sf\longmapsto x=(90)/(12)`

`\\ \sf\longmapsto x=7.5`

Answer 2

A ------- M -------- B

AM = 65

AB = 12x+40

AM + BM = AB

65 + X = 12x+40

65-40 = 12x-x

15 = 11x

x = 1.36

But in the question he should gave you BM
