Answer:
11 Combination of Coins
Step-by-step explanation:
You've answered part of the question already.
I'll continue from where you stopped.
Let D represents Dime
Let N represents Nickels
The answer starts from here
Let’s start by assuming he uses only 1
quarter.
D N
7 1
6 3
5 5
4 7
3 9
That’s 5 combinations.
Notice that the sum of each row is a consecutive number.
i.e 8,9,10...
Now, let's assume he's going to get both quarters.
For Dime,he has 10/2 possible dime for a start.
For nickel, we'll start from the least possible; 0
While Dime reduces by 1, Nickel increases by 2
So, we have
D N
5 0
4 2
3 4
2 6
1 8
0 10
That's 6 combinations
Total Possible Combination = 5 + 6
Total Possible Combination = 11 Combinations
Answer:
Step-by-step explanation:
<u>The first group consists of Petra and 4 friends, so the total number of members is 5, therefore the left side of equation should be:</u>
<u>The second group consists of 4 people, Valentina and 3 friends, therefore the right side of the equation should be</u>:
<u>Solving the equation to find the cost of a ticket for Petra's group:</u>
- 5(x + 5.5) = 4(1.5x + 4.75)
- 5x + 27.5 = 6x + 19
- 6x - 6x = 27.5 - 19
- x = 8.5
Cost of a ticket is $8.5

X=23 First, you have to subtract 12 by 12 to cancel it out. Next, you have to do the same thing to 20.05. 20.05 minus 12 is 8.05. All you have left is .35x. To get rid of the this you have to divide .35x by .35. Now all you have left is x. Finally you have to do the same thing to 8.05. 8.05 divided by .35 is 23. So, x=23
