First you subtract 3 from both sides, so:
6x+3=18
-3. -3
6x=15
Then divide both sides by 6:
x=2.5
Hope this helps!

<span>6*x+3-(18)=0 
</span>6x - 15  =   3 • (2x - 5)
Solve  :    2x-5 = 0 Solve :    3   =  0
dd  5  to both sides of the equation :<span> 
 </span>                     2x = 5 
Divide both sides of the equation by 2:
                     x = 5/2 = 2.500<span> 
hope that helps!!!

Amiraneli [1.4K]

Answer:

<h2>By angle sum property:</h2>

BAC+ABC+BCA=180°

90°+45°+x=180°

135°+x=180°

x=45°=BCA

<h2>since BCA=ABC=<u> </u>45° each </h2><h2>therefore,</h2>

AB=AC \\ (isosceles \: triangle \:  \\ theorem)

exis [7]

In the research, the distribution is described by its shape. If there are more higher values than lower values, the distribution is skewed left.

<h3>How to illustrate the research?</h3>

It should be noted that when the distribution of data is skewed to the <u>left</u>, the mean is less than the median.

The distribution can be described by its center. If the distribution is skewed left or right, the <u>median</u> is an accurate measure of center.

The distribution can be described by its spread. If the data set does not have an outlier, the interquartile range is an accurate measure of spread.
