Let x = the first number
x+1 = the second number
The sum of our two numbers is therefore: x + (x+1)
When you subtract 13 from the above you get 18 left over.
So our equation is:
x + (x+1) - 13 = 18
Now we can just solve for x:
x + (x+1) = 31
2x + 1 = 31
2x = 30
x = 15
So our first number is 15 and our second number must be 16.
-28. It’s underwater which is -20 and went -8 more feet down.
The first roll has 6 possible outcomes.
For each of those, the second roll has 6 possible outcomes, so there are 6×6 = 6² outcomes for two rolls.
For each of those, the third roll has 6 possible outcomes, so there are 36×6 = 6³ outcomes for three rolls.
The pattern continues, so for 8 rolls, there are 6⁸ = 1,679,616 possible outcomes.
