The universally accepted film size for movies has a width of 35 millimeters. If you want to project a movie onto a square sheet

dlinn [17]

Answer:

<h2>The scale factor is 285.7143 ≅ 286.</h2>

Step-by-step explanation:

The square sheet has an area of 100 square meters.

Hence, the width of the sheet is $\sqrt{100} = 10$ meters.

The scale factor is needs to be in such a way, so that the film's wide will be match perfectly with the square sheet. Hence, 35x millimeters = 10 meters = 10000 millimeters .

$x = \frac{10000}{35} = 285.7143$ .

Solve the systems of equations by substitution. 2x+y=-2 3x-y=7

lukranit [14]

Answer:

To solve the system of equations by substitution:

2x+y=-2

3x-y=7

first solve for y:

2x+y=-2

y=-2x-2

Then plug ^^ equation for y in the other equation

3x-(-2x-2)=7

5x+2=7

5x=5

x=1

Then solve for y:

2(1)+y=-2

y=-4

Final answer is x = 1 and y = -4

Hope it helps!
