Answer:
{x,y} = {6/5,23/10}
Step-by-step explanation:
[1] 7x + 2y = 13
[2] 4x + 4y = 14 <---------- linear equations given
Graphic Representation of the Equations : PICTURE
2y + 7x = 13 4y + 4x = 14
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 4y = -4x + 14
[2] y = -x + 7/2
// Plug this in for variable y in equation [1]
[1] 7x + 2•(-x +7/2) = 13
[1] 5x = 6
// Solve equation [1] for the variable x
[1] 5x = 6
[1] x = 6/5
// By now we know this much :
x = 6/5
y = -x+7/2
// Use the x value to solve for y
y = -(6/5)+7/2 = 23/10
// Plug this in for variable y in equation [1]
[1] 7x + 2•(-x +7/2) = 13
[1] 5x = 6
// Solve equation [1] for the variable x
[1] 5x = 6
[1] x = 6/5
// By now we know this much :
x = 6/5
y = -x+7/2
// Use the x value to solve for y
y = -(6/5)+7/2 = 23/10
It is NOT possible to determine the missing value from the given data.
<h3>Mean and Median</h3>
Mean is the average of a number of data while the median is the number at the middle of the given data.
- For a given data with a missing value, we can only find the missing value by calculating the mean of the data and equating the given mean.
Hence from the given data, it is NOT possible to determine the missing value from the given data.

The measure of center best represents the data set is Mean or Median.
Given
Data Set Best Measure of Center {27, 29, 26, 28, 25}.
<h3>What is the mean of the data set? </h3>
The mean is the average of a set of data.
The mean is found by finding the sum of the data and then dividing the sum by the number of data.
<h3 />
The mean of the given data set is;

Arranging the data set in the ascending order
{25, 26, 27, 28, 29}
The median is defined as the middle value of the given data set.
The median of the data set is 27.
Hence, the measure of center best represents the data set is Mean or Median.
