Answer:

fourth option

Step-by-step explanation:

Given the 2 equations

y = 2x - 3 → (1)

x + y = 18 → (2)

Substitute y = 2x - 3 into (2)

x + 2x - 3 = 18

3x - 3 = 18 ( add 3 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Substitute x = 7 into (1) for corresponding value of y

y = 2(7) - 3 = 14 - 3 = 11

Solution is x = 7, y = 11

Answer:

$\frac{3}{500}$

Step-by-step explanation:

Start by converting 5 meters to centimeters. Note 1 meter = 100 centimeters.

We can set up a unit converter:

$5m(\frac{100cm}{1m})$

The meters cancel out leaving us with:

$5*100cm=500cm$

The scale factor is:

$\frac{drawing}{real\ life}=\frac{3cm}{500cm}=\frac{3}{500}$
