Answer:
Die= 6 possible outcomes
spinner= 4 possible outcomes
word= 4 possible outcomes
alphabet= 26 possible outcomes
cards= 15 possible outcomes
Number of cards of John: J
Number of cards of Alan: A
<span>John and Alan have a collection of x baseball cards:
J+A=x (1)
</span>John has x/4 cards:
J=x/4
<span>What fraction of the cards does Alan have?
</span>
Replacing J by x/4 in the equation (1)
(1) J+A=x
x/4+A=x
Solving for A:
x/4+A-x/4=x-x/4
A=4x/4-x/4
A=(4x-x)/4
A=3x/4
Answer: Alan has 3/4 of the cards
Let us denote the years of Mary with M and the years that Al have with A.
<span>We know that the sum of Mary and Al's age is 48. So, we can write:
M+A=48 (1)
</span><span>We also know that twelve years ago, Mary was twice as old as Al.
So we can write:
M-12=2*A (2)
From the first equation (1): M=48-A
Let put this in the second equation:
48-A-12=2A
36=3A
A=12
M=48-12=36
</span>
