Answer:
26
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees, use this and set up an equation;
x + ( 4x -5 ) + 55 = 180
Simplify
x + ( 4x - 5 ) + 55 = 180
5x + 50 = 180
Inverse operations;
5x + 50 = 180
-50 - 50
5x = 130
/5 /5
x = 26
The sum of -5a and 3 is greater than 1
First step is to order the data from least to greatest.
10.5 11 11.5. 14.5 14.5 17 17 18 19
The median (Q2) is the middle number 14.5, this separates the lower half from the upper half. Q1 is the middle of the lower half, since there are an even amount of data, you have to take the average of the two middle numbers, 11 & 11.5, that would be 11.25; now we have to do the same with the upper half to find Q3, the average between 17 & 18 is 17.5
Now to find the IQR, subtract Q3 - Q1,
17.5 - 11.25 = 6.25
IQR = 6.25
Hi!
<h3>We need to isolate b on one side. </h3>
<em>Multiply by 4 on both sides. </em>
-83 * 4 = b/4 * 4
<u>-332 = b</u>
<h2>The answer is b = -332</h2>
<em>To check your answer, put in the value of b. </em>
-83 = -332/4
-83 = -83
<u>This equation is correct. </u>
Hope this helps! :)
