×

, which equals to 

The probability of eating two green candies is 

×

 which equals to 
 
 
        
        
        
180 - 124 = 56
4x = 180 - (56 + 60)
4x = 180 - 116
4x = 64
x = 16
answer
B. 16

Answer:
Larger number: 
16
Smaller number 
3
Step-by-step explanation:
Larger number: 16
Smaller number: 3
Explanation:
Suppose the larger number is 
a
 and the smaller number is 
b
.
You solve the following system of equations:
a⋅b=48
a−13=b
Since b is a −13, you can plug that into a⋅b=48, so...a⋅(a−13)=48 
a 2−13a=48
a2−13a−48=0
Factor the polynomial:
(a−16)(a+3)=0
a=16 or a=−3a is positive so a=16.
We can now solve for b by plugging in a, so...16−13=b3=b We have a=16 and b=3, meaning that the larger number is 16 and the smaller number is 3.
