Answer:
Let X be the number of customer purchased coffee
Let Y be the number of customer purchased donuts
Then
is the number of customer purchased both coffee and donuts
is the number of customer purchased both coffee or donuts
<em><u>The Number of customers purchased only Coffee:</u></em>
Number of customers purchased only donuts =n(X -Y)

n(X-Y) = 59 -16
n(Y - X) = 43
<em><u>The Number of customers purchased only donuts:</u></em>
Number of customers purchased only donuts =n(Y -X)

n(Y - X) = 39 -16
n(Y - X) = 23
<u>The Number of customers did not purchase either of these items:</u>
Number of customers did not purchase either of these items = 
First lets find 



=
= 28
Answer:
The rectangle has a width of 18 inches and a height length of 8 inches.
Step-by-step explanation:
The perimeter of a rectangle is described by the equation:

where <em>l</em> is width, <em>h</em> is height, and <em>p</em> is perimeter.
We're also told that the total perimeter is 52 inches.
We're also told that the length is six inches less than three times the width. We can express that as
.
We can plug that definition of w into the perimeter equation to find the length:

Now we can take that and the given perimeter, and substitute those into the perimeter equation to find the width:

So the width is 18
NO. IM SORRY. I DID NOT MEANT THAT. DONT TRUST MY ANSWER.

V=s/t
s=300 km = 300000 m
t=1 h and 30 min = 5400 sec
v=300/1,5= 200 km/h
or
v=300000/5400=55,5 m/s
