Is the equation True, False, or Open?

1 answer:

5 0

1. True
Explanation: (12+8) = 20 . . . 20/10 = 2 and 12/6 = 2

2. False
Explanation: 3(-6) = -18+5 = -13 . . . 26-3 = 23

3. I'm not quite sure about this one, but here's what I got:
Explanation: 8x-3 /8 = x=3/8 . . . 10x-1 /10 = x=-1/10

Also with the "open" option I've never heard of that option before so I'm not sure about that answer choice.

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:
$am=43$
