2x - 6 = 18
2x = 18 + 6 (24)
2x = 24
x = 12

<span>3x + 9 = 2x + 24
3x + 9 = 2x + 24 - 9 (2x + 15)
3x = 2x + 15
3x - 2x = 15
x = 15

</span><span>4x = 2.4? 0.4x = 2.4? I can't tell what the question is. Let me know in the comments and I'll answer it.
</span>
<span>5x + 4 = 24
5x = 24 - 4 (20)
5x = 20
x = 4

</span><span>2x / 3 = 4
2x = 4 * 3 (12)
x = 6

</span><span>3(x + 7) = 51
3x + 21 = 51
3x = 51 - 21 (30)
3x = 30
x = 10

Hope I helped :)</span>

Hey Guys! I need some help. This is the question... Sara travels often for her job. The miles she traveled for the last seven wo
Schach [20]

Using the median concept, it is found that the interquartile range of Sara's daily miles is of 21 miles.

<h3>What are the median and the quartiles of a data-set?</h3>

  • The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
  • The first quartile is the median of the first half of the data-set.
  • The third quartile is the median of the second half of the data-set.
  • The interquartile range is the difference of the quartiles.

The ordered data-set is given as follows:

65, 72, 86, 88, 91, 93, 97

There are 7 elements, hence the median is the 4th element, of 88. Then:

  • The first half is 65, 72, 86.
  • The second half is 91, 93, 97.

Since the quartiles are the medians of each half, the have that:

  • The first quartile is of 72 miles.
  • The third quartile is of 93 miles.
  • The interquartile range is of 93 - 72 = 21 miles.
