x is the number of adults and y is the number of children.
x + y = 12
<span>14x + 10y = 140
lets multiply the first equation by -10 and then add it to the second equation:
-10x - 10y = -120
</span>14x + 10y = <span>140
</span>-----------------------
4x + 0 = 20
x = 20/4
x = 5
then substitute in the original equation:
x + y = <span>12
</span>5 + y = <span>12
</span>y = 12 - 5
y = 7
therefore there were 5 adults and 7 children
10 because there is 4 zero's behind the one. Hopes this helps!! :)

Answer:
Option d is correct.
The number of students that chose Target as their favorite store over Ross = 4 students.
Step-by-step explanation:
The graph of the question is obtained from another brainly question on here. But uploading it will lead to deletion of this answer as it would be violating the community guidelines here.
So, I'm going to describe the graph.
The graph provided with the question is a pie chart, with each region clearly shown and the corresponding percentage for each of the students' favourite stores that come up in the survey given as
TJMax - 20%
Wal-Mart - 25%
Ross - 20%
Target - 25%
Others - 10%.
How many more students surveyed chose Target as their favorite store over Ross?
Total number of students sampled = 80
Number of students that picked Target
= 25% × 80 = 20 students
Number of students that picked Ross
= 20% × 80 = 16 students.
Number of students that chose Target as their favorite store over Ross = 20 - 16 = 4 students.
Hope this Helps!!!
Answer:
When we reflect a point across an axis, the distance between the point and the axis stays the same, but is flipped to the opposite side.
We know that the coordinates of point A are (4,1), the coordinates of point B are (6,3), and the coordinates of point C are (2,4).
In this case, Triangle ABC is a reflection of point A'B'C' across the y-axis.
