Mr. Anders was three times as old as Kate 5 years ago. Their total age now is 42 years. How old is Kate now?
katrin [286]
We can write this as two equations. Call Mr. Anders' age A and Kate's age K:
A-5=3(K-5)
A+K=42

Then solve for A in the second equation:
A=42-K

Substitute this into the first equation:
(42-K)-5=3(K-5)
-K+37=3K-15
52=4K
K=13

1/36 because you have 36 different possibilities when rolling it twice and getting and a 4 then a 6 is only 1 possibility out of the 36
1/4 because there is 3/6 chance on one roll and second roll
We said with 2 rolls there is 36 possibility (6x6)
So 3x3=9 which the amount of possibility to get a even number
9/36 simplify is 1/4 (divided by 9 the top and bottom)
Hope this helps!
