Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. Suppose there are twice as many student tickets sol
nikitadnepr [17]

Answer: the number of adult tickets sold is 400

the number of student tickets sold is 200

Step-by-step explanation:

Let x represent the number of adult tickets sold at the play.

Let y represent the number of student tickets sold at the play.

Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. If the income from the play was $1,700, it means that

1.75x + 1.25y = 1700 - - - - - - - - - -1

Suppose there are twice as many student tickets sold as adult tickets. This means that

y = 2x

Substituting y = 2x into equation 1, it becomes

1.75x + 1.25 × 2x = 1700= 1700

1.75y + 2.5y = 1700

4.25y = 1700

y = 1700/4.25 = 400

x = y/2 = 400/2 = 200

56. Suppose you wish to make a scale drawing of your living room,
Deffense [45]

Answer: 8.33\ in

Step-by-step explanation:

You know that the longer side of your living room is 25 feet and the shorter side of your living room is 18 feet.

 Then, knowing that in the scale drawing the shorter side is 6 inches, you can say that the scale factor is:

scale\ factor=\frac{18}{6}\\\\scale\ factor=3

<em>Let be "x" the longer side of the scale drawing in inches.</em>

 In order to find it, you must divide the actual longer side of you living room by the scale factor calculated above. Then you get:

x=\frac{25}{3}\\\\x=8.33\ in
