Answer: The correct option is C

X value is between 2 and 7 on number line.

Step-by-step explanation:

Given compound inequality is -6<3x-12<9

To simplify the inequality:

Step1 : Add 12

-6+(12)<3x-12+(12)<9+(12)

6<3x<21

Step2: Divide by 3

$\frac{6}{3}$

2<x<7

Therefore, X value is between 2 and 7 on number line.

The correct answer is C

First you have to label the other number , example : Ones, Tens, Hundreds
_______________________________________________________

5 9 . 5 3 3 | Start at the end , the number 3 , So it's 3= Ones , 3 , Tens , 5= Hundreds , There is a decimal so start over = 9= Ones

The number Nine is just 9 , because it's in the ones place and if it's in the ones place most of the time it stays the same.

The chord- chord angle is half the sum of the arcs intercepted by the angle and its vertical angle, that is

x = $\frac{1}{2}$ (92 + 50) = 0.5 × 142 = 71
