The perimeter of an airplane ticket is 32 centimeters. The area is 60 square centimeters. What are the dimensions of the ticket
victus00 [196]
We model the ticket as a rectangle.
 For this case what you should know is that the perimeter of the rectangle is given by:
 P = 2w + 2l
 The area of the rectangle is given by:
 A = w * l
 In both cases:
 w: width
 l: long
 We have the following system of equations:
 32 = 2w + 2l
 60 = w * l
 Solving the system we obtain:
 The dimensions of the ticket are:
 (10 cm) * (6 cm)
 Answer:
 the dimensions of the ticket are:
 (10 cm) * (6 cm)
 Note: see attached image for system solution

How many solutions does the system of equations have?(1 point)
nataly862011 [7]

Answer:

c

Step-by-step explanation:

First, I'll isolate the x in x+4y=5 to match with the other equation.

The new equation would be x= -4y+5

Next, we will multiply one equation by 3 and the other by -1 for both to match with the other.

-1(-12y + 15 = 3x )

3(-4y + 5 = x)

The new equations would be :

12y - 15 = -3x

-12y + 15 = 3x

Add the equations and you get

0 = 0

The equation has an infinite amount of solutions
