Answer:
The numbers are 40 and 22
Step-by-step explanation:
Let x and y be the two numbers; let x be the smaller number
x+y = 62
x = y-18
x+y = 62 becomes:
y-18+y = 62
2y-18=62
2y=80
y=40 (larger number)
x= y-18 = 40-18 = 22
Thus making the answers 40 and 22.

Answer: 720</h3>
=========================================================
Explanation:
We have 6 slots to fill A,B,C,D,E,F
There are 6 choices for choice A, then 5 choices for slot B, 4 for C, and so on until we reach one choice for slot F. Count down by 1 each time a slot is filled.
Multiply out those values to get: 6*5*4*3*2*1 = 720

Another approach is to use the nPr permutation formula which is
where in this case n = 6 and r = 6.
