Answer:
x = 
Step-by-step explanation:
Given
5(a - 2x) = 9(x + 1) ← distribute parenthesis on both sides
5a - 10x = 9x + 9 ( add 10x to both sides )
5a = 19x + 9 ( subtract 9 from both sides )
5a - 9 = 19x ( divide both sides by 19 )
= x
21, 19, 25, 23

Answer:
Segment bisector = KL
IJ = 11⅓
Step-by-step explanation:
Segment KL cuts segment IJ into two equal parts. Therefore the segment bisector of IJ is said to be segment KL.
Length of IJ:
From the figure given, the bisector divided the IJ into two equal parts. 1 part is given as 5⅔, therefore, the 2 parts joined together will give us lenght of IJ.
Thus, IJ = 2*5⅔ = 2 * 17/3 = 34/3 = 11⅓
Segment bisector = KL
IJ = 11⅓
Option B:

Solution:
Given expression:

To write this expression without negative exponents:

Using exponent rule: 



Substitute these in the expression.

Denominator of fraction in denominator goes to numerator.
Denominator of fraction in numerator goes to denominator.
Therefore,
goes to numerator and
goes to denominator.


Option B is the correct answer.
