Tickets to Dundee crowns mr.dchs are $3 for students and $5 for adults. The number of adult tickets sold was 195 more than the n

Maurinko [17]

Answer: number of tickets sold to adult = 566

Step-by-step explanation:

Let x = number of tickets sold by DCHS to students.

Let y = number of tickets sold DCHS to adults.

Tickets to Dundee crowns mr.dchs are $3 for students and $5 for adults.

This means cost of total tickets sold to students and adults is $3x and $5y respectively.

If DCHS collected $3943 for the tickets, then we have

3x + 5y = 3943 - - - - - -1

The number of adult tickets sold was 195 more than the number of student tickets. This means

y = x +195.

Put y = x +195 in equation 1

3x + 5(x+195) = 3943

3x + 5x + 975= 3943

8x +975=3943

8x = 3943-975= 2968

x = 2968/8 = 371

y = 371 + 195= 566

Your friend calculates the distance between points Q(1,5) and R(3,8), as shown below. What is his error?

borishaifa [10]

The distance between two points is the number of units between them.

The distance between Q and R is 3.61 units

<em>It is impossible to determine your friend's error, because the steps are not given in the question. So, I will calculate the distance between Q and R, instead.</em>

<em />

The distance (d) between two points is:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

So, the distance QR is:

$QR = \sqrt{(1 - 3)^2 + (5 - 8)^2}$

$QR = \sqrt{(- 2)^2 + (- 3)^2}$

Evaluate exponents

$QR = \sqrt{4 +9}$

$QR = \sqrt{13}$

Take square root of 13

$QR = 3.61$

Hence, the distance between Q and R is 3.61 units
