31=2y-5
Add 5 on both -5+5 which cancels out and 31+5 which is 36 and then divide 36 by 2 which equals to 18.
So y=18 hope this helped (':
 
        
                    
             
        
        
        
Answer:
Length = 6.25 feet
Step-by-step explanation:
Your dad is designing a new garden for your backyard. He has 20 feet of fencing to go around the garden.
Let the width is x. 
Length is 2 1/2 feet longer than the width i.e. (x+2 1/2) = (x+2.5) feet
Perimeter = 20 feet
2(l+b) = 20
(l+b) = 10
(x+2.5+x) = 10
2x+2.5 = 10
2x = 7.5 
x = 3.75 feet
Length = (x+2.5) 
= (3.75+2.5)
= 6.25 feet
So, the length of the garden is 6.25 feet.

First turns those into fractions, now you should have 4/5 and 1/5.
Now to generate a chance the 2 events will happen in a row (Like rain and a postponed game) you need to multiply the 2 fractions together so it should come out with 4/25 or 16%
