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
Answers
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

graph the inequality plz help me solve this and explain how plzzzzzz x-y <4
Answers
Answer:
Step-by-step explanation:
first you have to get the inequality to a point where you can actually graph it
to do this you have to get the x to the same side of the less than symbol
you do this like any other equation, subtract x from the left and right sides because whatever you do to one side, you do to the other
this leaves you with -y < -x + 4
you have to multiply the entire thing by -1 because y cannot be negative
this gives you y < x - 4, now you can graph it
because x is isolated you just have to graph y < -4 like so
im not the best at explanations, i apologize
Rebecca Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 863 points. The number of two-point field goals that Rebecca made was 80 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 13 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Rebecca Smith made during the 2006 regular season.
Answers
Answer:
Number of free throws = 155,
Number of two-points field goals= 168
Number of two-points field goals= 124
Step-by-step explanation:
Let x,y, and z be the numbers of free throws, two-point field goals and three-point field goals she made.
As she scored a total of 863 points, so
x+2y+3z=863...(i)
As the number of two-point field goals that Rebecca made was 80 less than double the number of three-point field goals she made, so
2z-y=80
Or y=2z-80...(ii)
As the number of free throws (each worth one point) she made was 13 less than the number of two-point field goals she made, so
y-x=13
-x= 13-y
-x= 13-(2z-80)
-x= 93-2z
x=2z-93...(iii)
Now, put the values from equation (ii) and (iii) to equation (i), we have
(2z-93)+2(2z-80)+3z=863
2z-93+4z-160+3z=863
9z=863+93+160=1116
z=1116/9=124
From equation (ii)
y=2x124-80=168
and from equation (iii)
x=2x124-93=155.
Hence, the number of free throws, two-point field goals, and three-point field goals Rebecca Smith made during the 2006 regular season are 155, 168, and 124 respectively.

what is x? in the equation x-21=6
Answers
Answer:
27
Step-by-step explanation:
You would turn the equation around, so it is 21+6=27 and checking, 27-21=6
Answer:
x = 27
Step-by-step explanation:
x- 21 = 6
add 21 to both sides:
x = 27
Check your work by substitution:
27 - 21 = 6
6= 6
x = 27
What does negative 3 over 5 > −2 indicate about the positions of negative 3 over 5 and −2 on the number line?
Answers
So,
Ignore the negatives and just make them positives.
For now.
Then, you look at 3/5 and say... it's 3 ticks towards the number five,
meaning it's between 4 and 5. After you do that whats happens is you place back the negatives and you have -3/5 and -2.
-2 < 5 and -2 < 4
Meaning it goes more to the left.

Answers
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.
