Answer:

<h3>#4</h3>

Let M is the midpoint of DE.

Since D is at 8 and DE = 5.

DM = ME = 5/2 = 2.5

<u>Point M is at:</u>

  • 8 + 2.5 = 10.5          if E is to the right of D
  • 8 - 2.5 = 5.5            if E is to the left of D
<h3>#5</h3>

<u>Given</u>

  • XY = 7,
  • YZ = 2x - 1,
  • XZ = 30

<u>Since XZ = XY + YZ, set up an equation and solve for x:</u>

  • 7 + (2x - 1) = 30
  • 2x + 6 = 30
  • 2x = 24
  • x = 12
<h3>#6</h3>

The distance from your house to friend's is LN.

<u>We have: </u>

  • M is midpoint of LN, so LM = MN
  • LM = 3x
  • MN = 2x + 2

<u>Set up an equation, solve for x:</u>

  • 3x = 2x + 2
  • 3x - 2x = 2
  • x = 2

<u>Find the distance LM:</u>

  • LM = 3*2 = 6

<u>Find the distance LN:</u>

  • LN = 2*LM = 2*6 = 12

A. 5x - 2 = 8<br>b. 4x - 3= 2x + 9<br>C. 6x + 3 = 2x + 8​
Elena L [17]

Answer:

a) x=2

b)x=12

c)x=5/4

Step-by-step explanation:

a)5x-2=8

5x=8+2

5x=10

x=2

b)4x-3=2x+9

4x-2x=9+3

2x=12

x=6

c)6x+3=2x+8

6x-2x=8-3

4x=5

x=5/4

Proof:

a)5x-2=8

5(2)-2=8

10-2=8

8=8

b)4x-3=2x+9

4(12)-3=2(12)+9

48-3=24+9

45=45

c)6x+3=2x+8

6(5/4)+3=2(5/4)+8

30/4+3=10/4+8

15/2+3=5/2+8

10.5=10.5

Hope this helps ;) ❤❤❤

If mZMNO = 95°, mZADC = 101°, and mZMLO = 80°, then what is m/ABC, in degrees?
dem82 [27]

Answer:

This is your answer.

Step-by-step explanation:

There are different kinds of angles:

Angles below 90= Acute

90= Right

91–179= Obtuse

180= Straight Angle

181–359= Reflex Angle

360= Complete Angle or Circle.

Because 80 degrees is less than 90 degrees, Angle ABC is an acute angle.
