Point m is the midpoint of ab¯¯¯¯¯ . am=2x+9, and ab=8x−50. what is the length of am¯¯¯¯¯¯ ?
iogann1982 [59]
Since m is the midpoint of ab, then the following relationship is fulfilled:
 am =  \frac{ab}{2}
 Therefore, substituting values we have:
 2x+9 = \frac{8x-50}{2}
 From here, we clear the value of x.
 We have then:
 2x+9 = 4x-25
 9+25 = 4x-2x
 34 = 2x
 x =  \frac{34}{2}
 x = 17
 Then, the value of am, is given by substituting x in the expression:
 am=2x+9
 Substituting we have:
 am=2(17)+9
 am=34+9
 am=43
 Answer:
 
the length of am is:
 
am=43

Solve for x. Please:)
lutik1710 [3]

Answer:

  x = 3

Step-by-step explanation:

The smaller triangle and larger one are similar, so corresponding sides are proportional.

  8/4 = (8 +(x -1))/5

  10 = x +7 . . . . . . . . . multiply by 5 and simplify

  3 = x . . . . . . . . . subtract 7

__

<em>Alternate solution</em>

The short segments are also proportional:

  (x -1)/(5 -4) = 8/4

  x -1 = 2 . . . . simplify

  x = 3 . . . . . . add 1
