Let's put them in order.
22, 23, 24, 30, 31, 33
Now find the middle of the numbers.
22, 23, 24 ║30, 31, 33
31-23
8
So the IQR is 8.
18.5-0.5= 18
18/3= 6
So r=6
The given expression is
![2x](https://tex.z-dn.net/?f=2x%3C20)
We just have to divide by 2
![\begin{gathered} \frac{2x}{2}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B2x%7D%7B2%7D%3C%5Cfrac%7B20%7D%7B2%7D%20%5C%5C%20x%3C10%20%5Cend%7Bgathered%7D)
<h2>Hence, the solution is all real numbers less than 10.</h2>
Answer:
(4,19)
Step-by-step explanation:
Cuz if u substitute these values in for the x and y in the equation, the equation would be true:
1.) 19 <em>= </em>7(4) - 9
2.) 9 <em>≠</em> 7(54) - 9
3.) 30 <em>≠</em> 7(-3) - 9
4.) 15 ≠ 7(2) - 9
As you can see, 1st equation is the only equation that's true.
Hope this helps!
