Answer:
$180
Step-by-step explanation:
step one 86+4 =90
step two 90×2=180
<em>y= -3</em>
<em>x= 0</em>
I will give the explanation in picture, hope you can understand it.
7 miles
As, we will take unit rate as "x"
So, for one day = x distance
For 5 days = 5(x)
For 5 days she covered 35 miles
So therefore,
5(x) = 35 miles
X= 35/5
X=7 miles
For a day= 7 miles are covered
Let's first arrange it in ascending order :
340, 480, <u>560</u>, 680, 700
<u>560</u> is clearly the median.
Now add an additional score of 700 to the data :
340, 480, <u>560, 680</u>, 700 ,700
<u>560, 680</u> is separating both halves but is not the median
Median = (560+680)/2
= 1240 / 2
Median = 620
