Answer:
The answer is p= 2 and 1/3
Step-by-step explanation:
This answer can be found using the order of operations to solve for p. 
Start by distributing 2/3 by (5p-6)
add -4/3p to 10/3p equaling 6/3p or 2p
subtract 13 from both sides
-p= 2p - 7
p=2 and 1/3

It seems like you have the answer already. but heres how its calculated.
 
 so the missing number is 20 **cross multiply 100 and 3 to get 300 then divide 15 into 300 to get 20**
 
 so the missing number is 50
 **cross multiply 100 and 80 to get 8000 then divide 160<span> into 8000 to get 50**</span> 
 
        
        
        
13 is not a perfect square so it is (irrational)
