A group of 7 people spent $33.50 on movie tickets. They paid $6.50 for each adult ticket and $3.50 for each child's ticket. We would like to determine how many of each type of ticket was purchased. A. Specifically define variables for this system B. Write a system of equations that reflects the relationships described in this situation
Answer:
Number of Adult tickets = 3
Number of student tickets = 4
Step-by-step explanation:
Let the number of Adults tickets = x
The number of students tickets = y
A. Specifically define variables for this system
x + y = 7...... Equation 1
They paid $6.50 for each adult ticket and $3.50 for each child's ticket.
$6.50 × x + $3.50 × y = $33.50
6.50x + 3.50y = 33.50.......Equation 2
B. Write a system of equations that reflects the relationships described in this situation
x + y = 7...... Equation 1
x = 7 - y
6.50x + 3.50y = 33.50.......Equation 2
6.50(7 - y) + 3.50y = 33.50
45.5 - 6.5y + 3.5y = 33.5
45.5 - 33.5 = 6.5y -3.5y
12 = 3y
y = 12/3
y = 4 tickets
x + y = 7...... Equation 1
x + 4 = 7
x = 7- 4
x = 3 tickets

Find the two integers, m and n,
make the equation (2x^ny2)m = 4x6y4 true.
Answer:
m = 2 and n = 3
Step-by-step explanation:
We want to find the value of the integers m and n that will make the given expression true
(2x^ny^2)^m = 4x^6y^4
We can rewrite the left hand side of the equation as follows;
(2x^3y^2)^2
we can proceed to use inspection to ind the value of m and n
Through inspection since the left hand side of the equation now looks like the right hand side;
Then;
m= 2 and n = 3

Answer:
v=31
Step-by-step explanation:
Average speed is total distance/total time.
We can rearrange this equation to find total distance:
Distance = time x speed
Our given time is 14 hours and our average speed is 13km/h, therefore the distance travelled 14x13=182m.
On a speed-time graph, the distance is found by finding area under the line on the graph. So to find v, we can find the area for the other sections first and then use the remainder to find v.
The total distances for the other 3 sections are: 4x6 + 6x12 + 4x12 = 24+72+24=120
182-144 = 38
This means that the area of the triangle with height v-12 has an area of 38.
Area of a triangle = 1/2bh
38=1/2(4)h
38=2h
h=19
The distance between v and 12 is 19 so the full value of v is 19+12=31
v = 31

Anthony, Josh, and Dominic worked a combined 7 hours today. Dominic worked twice as many hours as Anthony did with an extra hour. Dominic worked 5 more hours than Josh did. How many hours did each of them work?
The number of hours worked by Anthony , Josh and Dominic is 2 hours , 0 hours and 5 hours respectively
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of hours worked by Anthony = A
Let the number of hours worked by Josh = J
Let the number of hours worked by Dominic = D
Total number of hours worked by Anthony , Josh and Dominic = 7 hours
So , A + J + D = 7 be equation (1)
Now ,
Dominic worked twice as many hours as Anthony did with an extra hour
So , D = 2A + 1 be equation (2)
And ,
Dominic worked 5 more hours than Josh did
So , D = 5 + J be equation (3)
Simplifying be equation (2) and be equation (3) , we get
2A + 1 = 5 + J
Subtracting 5 on both sides , we get
J = 2A - 4 be equation (4)
Now ,
Substituting the values of equation (2) , equation (3) and equation (4) in equation (1) , we get
A + 2A - 4 + 2A + 1 = 7
5A - 3 = 7
Adding 3 on both sides , we get
5A = 10
Divide by 5 on both sides , we get
A = 2
Therefore , the number of hours Anthony worked is 2 hours
Now , Substituting the value of A in equation (4) , we get
J = 4 - 4
J = 0 hours
Therefore , the number of hours Josh worked is 0 hours
Now , Substituting the value of A in equation (2) , we get
D = 4 + 1
D = 5 hours
Therefore , the number of hours Dominic worked is 5 hours
Hence , The number of hours worked by Anthony , Josh and Dominic is 2 hours , 0 hours and 5 hours respectively

Please identify the common angles and sides or if there are non. Explain all work please!
Answers:
Common angles: ΔBGC and ΔGDC
Common sides: ΔGE and ΔAG
A common angle is a triangle that exists in two or both of the triangles.
Here, the common angles should be ΔBGC and ΔGDC.
These two angles are triangles, and they consist in both triangles.
A common side is when two angles have one vertex in the same area.
Here, we see that the common sides are ΔGE, because they intersect.
Another common side we see here is ΔAG, because they also intersect.

A flat screen television measures diagonally 40 inches and 24 inches in length. What is the width of the television?
Answer:
The width of the television is 32 inches
Step-by-step explanation:
The given parameters are;
The diagonal length of the flat screen television = 40 inches
The length of the television screen = 24 inches
The width of the flat screen television is given by Pythagoras theorem as follows;
Diagonal² = Length² + Width²
Therefore;
Width² = Diagonal² - Length² =
Width² = 40² - 24² = 1024
∴ The width = √1024 = 32
The width = 32 inches
The width of the television = 32 inches.
