A total of tickets 569 were sold for the school play. they were either adult tickets or student tickets. there were 69 more stud

makkiz [27]

------------------------------------------
Define adult and student tickets
------------------------------------------
Let the number of adult tickets be x
Adult tickets = x
Student tickets = x + 69

------------------------------------------
Form equation and solve for x
------------------------------------------
x + x + 69 = 569
2x + 69 = 569 ← Combine like terms
2x = 569 - 69 ← Subtract 69 from both sides
2x = 500
x = 250 ← Divide by 2 to find x

------------------------------------------------------------------------------------
Find the number of adult tickets and student tickets
------------------------------------------------------------------------------------
Adult tickets = x = 250
Student tickets = x + 69 = 319

------------------------------------------------------------------------------------
Answer: Adult tickets = 250 ; Student tickets = 319
------------------------------------------------------------------------------------

Find the determinant of the following matrix. A =<br>-2 6<br>3 5

Blababa [14]

Answer:

$|A| = - 28$

Step-by-step explanation:

Given

$A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right]$

Required

Determine the determinant

For a two by two matrix, A such that:

$A = \left[\begin{array}{cc}a&b\\c&d\end{array}\right]$

The determinant |A| is:

$|A| = a * d - b * c$

So, in

$A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right]$

The determinant is:

$|A| = -2 * 5 - 6 * 3$

$|A| = -10 - 18$

$|A| = - 28$

What is the common ratio of the sequence -2,6,-18,54

sdas [7]

Common ratio, r is found by dividing the next term by the previous term

r = $\frac{6}{-2}$ = -3
you can see this value is true for any consecutive pairs of terms
also, multiply by -3 to get the next term

First one to answer, i will mark brainlist

7nadin3 [17]

Answer:

Sides in descending order: YZ > ZX > XY

Step-by-step explanation:

Sum of all angles of triangle = 180

104 +52 + ∠Z = 180

156 + ∠Z = 180

∠Z = 180 - 156

Z = 24

The sides opposite to the biggest is the longest side.

Angles in descending order: ∠X > ∠Y > ∠Z

<h3>Sides in descending order: YZ > ZX > XY</h3>
