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

A trough is filled with water. The trough holds 315 gallons. Each cubic foot of water contains about 7.5 gallons. The trough is
elena55 [62]

Answer:

The height of the trough is about 1.5 ft

Step-by-step explanation:

If each cubic foot of water contains about 7.5 gallons.

Then; 315 gallons is about \frac{315}{7.5}=42ft^3

Let h be the height of the trough, then

7\times 4\times h=42

This implies that;

28h=42

Divide both sides by 28 to get:

h=\frac{42}{28}

\therefore h=1.5

The height of the trough is about 1.5 ft
