Let's just choose "x" as our variable for the length of a side of the triangle. 
Two sides of a triangle are equal in length and double the length of the shortest side. 
A triangle has 3 sides. Make the smallest side x then the two equal sides that are double the smallest side are both equal to 2x
The perimeter of the triangle is 35 inches. Perimeter is the sum of all sides. 
x + 2x + 2x = 35 
5x = 35
x = 7 
So the smallest side is 7, and the other two sides are 14. 
 
        
             
        
        
        
Y = kx
72 = k*3
73/3 = k
24 = k
y = 24x
        
             
        
        
        
Answer:
?
Step-by-step explanation:
what am i tryign to solve here
 
        
             
        
        
        
3/4 = 3/4*1
3/4 = 3/4 * 3/3 = 9/12
Box is 9/12 full after heba ate 1/12 of a box of cereal
Initial fraction will be 9/12+1/12
=10/12= 5/6
