Lets say x is the smaller number and y is the bigger number.
x + y = 436
x + 134 = y
We can substitute the second equation into the first (substitute x + 134 in for y)
x + (x+134) = 436
2x + 134 = 436
2x = 302
x = 151
We can now plug this back into either formula (i use the second)
151 + 134 = b
b = 285
The 2 numbers are 151 and 285

Answer:
d. 11.6
Step-by-step explanation:
The results of the first die and the second one are independent to each other. The expected value of Z is obtained, therefore, by summing the expected values of both X and Y, because Z = X+Y and X and Y are independent. As a result 
It will be a negitive because positive numbers multiplied together will always make a positive, & an odd number of negitives make a negitive. and (-)x(+)=negitive.
Hope this helps :)
