Answer: 570 adult tickets and 215 children tickets were sold
Step-by-step explanation:
Let x represent the number of adult tickets that were sold for the movie Saturday.
Let y represent the number of children tickets that were sold for the movie Saturday.
One Saturday the theater sold 785 tickets. This means that
x + y = 785
The movie theater charges 5 for an adult ticket and 2 for a child's ticket. The total sales on Saturday was 3280. This means that
5x + 2y = 3280 - - - - - - - - - - --- 1
Substituting x = 785 - y into equation 1, it becomes
5(785 - y) + 2y = 3280
3925 - 5y + 2y = 3280
- 5y + 2y = 3280 - 3925
- 3y = - 645
y = - 645/- 3
y = 215
x = 785 - y = 785 - 215
x = 570
3x+2y=14
2x-4y=4
6x+4y=28
2x-4y=4
8x = 32
x = 4
2y = 14 - 12 = 2
y = 1
(x , y) = (4 , 1)
Question:How can check your solution by writing the system as a matrix equation and using the inverse matrix?.

2 −4] = (14
4) The left side can be called your "A" matrix. I gave you the idea so that you may continue with it. Hope this can help
Final answer:
To check the solution, represent the system of equations as a matrix equation, find the inverse of the coefficient matrix, and multiply both sides of the equation by the inverse.
Explanation:
To check the solution by writing the system as a matrix equation and using the inverse matrix, we need to represent the system of equations as a matrix equation. Let's consider the given system of equations:
3x + 2y = 14
2x - 4y = 4
To do this, we can write the coefficients and constants of the system of equations as matrices:
[3 2] [x] = [14]
[2 -4] [y] = [4]
Now, we can write the system of equations as a matrix equation: AX = B, where A is the coefficient matrix, X is the variable matrix, and B is the constant matrix.
Next, we need to find the inverse of matrix A. If the inverse exists, we can multiply both sides of the matrix equation by the inverse of A to find the solution for X.
If we find the inverse of A and multiply both sides of the equation by the inverse, we get:
X = A-1B
Substituting the values of A-1 and B, we can find X, which represents the solution to the system of equations. Therefore, we can check our solution by writing the system as a matrix equation and using the inverse matrix.

Answer:
$26,000.
Step-by-step explanation:
We have been given that a job that pays $100,000 per year federal income taxes 19% and state income tax is 7%.
The annual total of the required deductions of federal and state income tax would be .
To find the total amount, we will find 26% of $100,000.
Therefore, the annual total of the required deductions of federal and state income tax is $26,000.
Then multiply 100,00 and 7% equaling 7,000
Lastly add 7,000 and 19,00 together to get your answer

so, Vtotal = V(thermistor) + V(resistor)
5= 2 +Vr
Vr= 3 Volt
the current passing through the Resistor I= V/ R
so I = 3/1050
I=1/350 A
while the Resistor and thermistor are series the I(total) = I(thermistor) = I(resistor) = 1/350 A
Voltage at the thermistor = 2V
so r = V/ I
then R(thermistor) = 700 ohm
