Multiply the first equation by 3
21x+15y=-6
Add this to the second equation
21x+15y=-6
-21x-15y=6
0+0=0
True
Final answer: Infinitely Many Solutions (they are coinciding lines)
Answer is C= 52d
To solve problems like this, you would just need to think about what the question is asking you one step at a time
List what you know
- There are 52 cards in each deck
- We need how many cards in total
So let us think about it from a mathematical standpoint
1 deck= 52 cards 1 x 52= 52
that means.....
2 deck= 104 cards 2 x 52 = 104
3 deck= 158 cards 3 x 52 = 158
and the list keeps going
That means that 52 multiplied by whatever number d is will get you the total number of cards.
thus C= 52d
First box: 7 to the power of 2
second box: 7
third box: 7 to the power of four
first box: m to the power of 2
second box: m to the power of 5
The answer is w = 12 hope this helped:)
