Answer:
There are 38 premium tickets and 82 regular tickets in a pile.
Step-by-step explanation:
Given,
Total number of tickets = 120
Total amount = $5812
Solution,
Let the number of premium tickets be x.
And the number of regular tickets be y.
Total number of tickets is the sum of total number of premium tickets and total number of regular tickets.
So the equation can be written as;
Again,total amount is the sum of total number of premium tickets multiplied by cost of each premium ticket and total number of regular tickets multiplied by cost of each regular ticket.
So the equation can be written as;
Now We will multiply equation 1 by 25 we get;
Now Subtracting equation 3 from equation 2 we get;
We will now substitute the value of x in equation 1 we get;
Hence There are 38 premium tickets and 82 regular tickets in a pile.
Answer:
<em>The total price of the CD is $14.18</em>
Step-by-step explanation:
<u>Percentages
</u>
We can compute additive or subtractive percentages by using these formulas. If we have a number X and want to increase it by Y%, then the increase is xY/100. Thus the new value for the number is x+xY/100 or equivalently
If we want to decrease by Z%, the new value is
The regular price for a CD is X=$15. The CD is Z=10% off, so the sale price is
But we have to add the tax of Y=5%, so the final value is
The total price of the CD is $14.18
f(x)=9x²+24x+1
f(x)=(3x)²+ 2×3x× 4 + 1
= (3x)²+2×3x×4 +16 -16 +1
=. ( 3x+4)² -15. -------(1)
then (3x+4)² ≥0
least value of (3x+4)² is 0
putting in equation 1
= 0-15 =-15
- 15 is the least value
One person would be shaking 3 other peoples hands.
So, there's 3 handshakes right there. No you multiply that by 4.
Which is 12. So there are 12 handshakes happening.
Hope this helps. c:
Answer:
-28x(-1.6)
Step-by-step explanation:
combine like terms: -18x +(-10x) ---> <u>-28x</u>
3-4.6 ---> <u>-1.6</u>
Combine the leftover terms:
<u>-28x(-1.6)</u>
