Answer:
Step-by-step explanation:
we know two sides of a triangle, one side is 7 feet, the other is 12 feet , so use Pythagoras theorem
=
+ 
=
+ 
= 49 + 144
= 193
C = 
C = 13.89 feet
I think you solved it on your own because x is 82
Data:
x y
16 4
32 16
48 36
Direct relation means that the ratio y / x is constant.
So, let's examine this ratio:
Ratio y / x
4/16 = 1/4
16/32 = 1/2
36/48 = 3/ 4
Given that the ratio y/x is not constant, the conclusion is that y does not vary directly with x.
5n = 25
divide both sides by 5
n = 5
180=(9X-11)+(4X+1)+(7X-3)
180=20x-13
193=20x
9.65=x
