Answer: 220
<u>Step-by-step explanation:</u>
Children (x): $2
Teens (y): $3, 
Adults: (z): $5
Quantity: x + y + z = 570 ⇒ x + + z = 570 ⇒ 1.75x + z = 570
Cost: 2x + 3y + 5z = 1950 ⇒ 2x + 3
+ 5z = 1950 ⇒ 2x + 2.25x + 5z = 1950 ⇒ 4.25x + 5z = 1950
Qty: 1.75x + z = 570 → 5(1.75x + z = 570) → 8.75x + 5z = 2850
Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → <u> -4.25x - 5z</u> = <u>-1950 </u>
4.50x = 900
x = 200
Teens (y):
y = 
= 
= 150
Quantity: x + y + z = 570
200 + 150 + z = 570
350 + z = 570
z = 220
Answer:
The answer is A .
Step-by-step explanation:
Hope it helps u , good luck ^.^
The equation of the line that is parallel to the given line, through the given point is y = -5x - 7
Given equation,
y = -5x + 1
Slope = m
= -5
For two lines to be parallel, slope is equal.
Therefore, m = -5 for another line.
Let the equation of the line be y = mx + c
This line passes through A(-2,3)
Therefore, 3 = -5(-2) + c
3 = 10 + c
c = 3 - 10
= -7
Hence, equation of line is y = -5x - 7.

Answer:
![[4,0,3,1,2,5]](https://tex.z-dn.net/?f=%5B4%2C0%2C3%2C1%2C2%2C5%5D)
and ![[6,9,8,7]](https://tex.z-dn.net/?f=%5B6%2C9%2C8%2C7%5D)
Step-by-step explanation:
GIVEN: an array of ten integers 
.
TO FIND: If we partition this array using Quick sort's partition function and using 
for the pivot. List the elements of the resulting array after the partition finishes.
SOLUTION:
quick sort is a divide and conquer algorithm in which an array is partitioned into sub-arrays about an pivot element by checking whether elements are greater than pivot or and then sub arrays are sorted recursively.
Here is the pivot element.
two arrays will be created, in first array element less than or equal to pivot element are stored in other elements greater than pivot element are stored.
Starting from first element of array
elements in first array will be ![=[4,0,3,1,2,5]](https://tex.z-dn.net/?f=%3D%5B4%2C0%2C3%2C1%2C2%2C5%5D)
elements in second array will be ![=[6,9,8,7]](https://tex.z-dn.net/?f=%3D%5B6%2C9%2C8%2C7%5D)
Hence the resulting array after the partition finishes are and
The answer is 68
hope this helps
