Answer:

x = 8

Step-by-step explanation:

Create the expression:

10(x + 10) = 9(9 + 11)

Do PEMDAS (Parenthesis):

10(x + 10) = 9(20)

Do PEMDAS (Multiplication):

10x + 100 = 180

Cancel out:

10x + 100 = 180

        -100   -100

10x = 80

Simpilfy:

x = 8

If AC=38 3/4,AB=6x, BC=8x+1/4 <br> what’s the value of x?
azamat

Applying the segment addition postulate:

x = 2.75

AB = 6x = 6(2.75) = 16.5 units

BC = 8x + 1/4 = 8(2.75) + 1/4 = 22.25 units.

<h3>What is the Segment Addition Postulate?</h3>

Based on the segment addition postulate, since B lies between points A and C on a line segment, then:

AB + BC = AC

AC = 38 3/4

AB = 6x

BC = 8x + 1/4

Substitute

6x + 8x + 1/4 = 38 3/4 [segment addition postulate]

14x + 1/4 = 155/4

14x = 155/4 - 1/4

14x = (155 - 1)/4

14x = 154/4

14x × 4 = 154

56x = 154

x = 154/56

x = 2.75

AB = 6x = 6(2.75) = 16.5 units

BC = 8x + 1/4 = 8(2.75) + 1/4 = 22.25 units.

0.078, 0.708, 0.78, 0.87.

The further down the number is after the decimal point , the smaller it is; for example, 0.005 is smaller than 0.05. Hope that helped.
