Answer: y=15/x
For this problem you need to use trial and error.
For the first equation, 15-14 does equal 1, but 5-14 doesn’t equal 3. For the second equation, 15x15 doesn’t equal 1. For the third equation, 15+2 doesn’t equal 1. For the last equation, 15/15 is 1, 15/5 is 3, and so on. So, the last equation shows the relationship in the table.

Answer:
Perimeter is irrational

Step-by-step explanation:
<em>The attachment is missing but the question is still answerable</em>
Given
Required
Determine if the Perimeter is rational or not
First, we need to determine the sides of the square;
Substitute
Take Square root of both sides
The perimeter of a square is calculated as:
<em>Because the value of </em><em>perimeter </em><em>can't be gotten by dividing two integers, then </em><em>perimeter is irrational</em>
117, just add the two and subtract from 180
We know that y is equal to x-2. We can just substitute x-2 for y since y is equal to it.
10x- 9(x-2)=24
Distribute.
10x- 9x+18= 24
x+18= 24
Subtract 18 on both sides.
x= 6
Now, plug in x.
y= (6)-2
y= 4
We can check this to see if this works:
4= 6-2, 4=4
10(6)- 9(4)= 24
60-36= 24, 24=24
x=6 and y=4
I hope this helps!

First question
Volume = height * radius*radius*3.14
5*3*3*3.14 = 141.3 in3
Second qustion
Violume = height * radius * radius * 3.14
28*8*8*3.14= 5626.88 cm3
So the answer is 1875.63 because it's the closest
