The aspect ratio of a TV screen is the ratio of the width to the height of the image. A regular TV has an aspect ratio of 16: 9.

ki77a [65]

Answer:

Width = 44.45 inches

Height = 25.00 inches

Step-by-step explanation:

(16x)^2 + (9x)^2 = 51^2

256x^2 + 81x^2 = 2601

337x^2 = 2601

x^2 = 7.718

x = 2.778

Width = 44.45 inches

Height = 25.00 inches

I think this is right

Write and solve the system of linear equations described by the application and then answer the question. One hundred sixty feet

Lena [83]

Answer:

80 ft x 40 ft

Step-by-step explanation:

Let 'L' be the length of the longer side and 'W' be the length of the shorter side (or the width).

The equations that compose the linear system are:

$L+2W=160\\L=2W$

Solving the system:

$L+L=160\\L=80\\W=\frac{L}{2}\\W=40$

The garden is a rectangle with dimensions 80 ft x 40 ft.
