 B.<span>Adding 15 to both sides of the equation. 

A. Adding 8x to both sides wouldn't cancel anything out. 
B. Adding 15 to both sides will cancel out 15 making it easier to solve for x.  
C.Adding 3 to both sides will not cancel anything out.
D. Adding 2x to both sides won't cancel anything out. </span>

Complete the statement, and find the value of x in the diagram. A trapezium with two opposite angles is labeled as 101 degrees.

The complete statement about the quadrilateral is, the quadrilateral shown is a kite and the value of x is 3

<h3>What are quadrilaterals?</h3>

Quadrilaterals are shapes that have four sides and four angles.

The four sides may or may not be congruent, and at the same time the four angles may or may not be congruent

<h3>How to determine the value of x?</h3>

The image that completes the question is added at the end of this solution as an attachment

From the attached figure, we have the following highlights

  • Opposite angles of the quadrilateral are congruent
  • Adjacent sides of the quadrilateral are congruent

This means that:

AD = DC

AB = BC

The quadrilateral shown is a kite

So, we have the following congruent angles:

ADB = CDB

Substitute the measure of both angles

11x = 9x + 6

Subtract 9x from  both sides

3x = 6

Divide both sides by 2

x = 2

Hence, the complete statement about the quadrilateral is, the quadrilateral shown is a kite and the value of x is 3

If you mean each minute she read 3 pages.



If she started on page 20 and read 3 pages every minute, and the answer is how many pages did she read in 9 minutes.
Simple just do 20 x 9.

First step - what’s 2 x 9...18. Now anytime there’s a zero just simplify it by putting the 0 at the end of your answer. So the answer would be 180.

I hope this helped!!!
