(14) There are 4 Aces and 4 Kings in a standard deck of cards
I will show you how to solve by elimination. You have two equations. The goal of this method is to cancel out one of the variables.
3y=x-1
x-2y=2 ----> 2=x-2y (just flipping it around visually)
If we align the two equation and subtract them...
-(2=x-2y) "x is canceled out"
---------------
3y-2=-1+2y "one variable equation now"
y=1
Plug in 1 for y into any equation to get corresponding x value.
3(1)=x-1
x=4
Answer: (4,1)
7/12.
Step-by-step explanation:
The favourable outcomes are (1,6), (2,5), (2,6), (3,4), (3,5), (3,6) (4,5), (4,6) (5,6),
(6,1), (5,2) (6,2) (4,3) (5,3) (5,4) (6,3) (6,4) (6,5) (4,4) (5,5) (6,6)
= 21.
Total number of possible outcomes = 6*6 = 36.
So it's 21/36
= 7/12.
The answer is $44.10. You times 42 by 0.05 and then add that answer to 42 and you get 44.10
