Answer:

8x + 20y = 5

Step-by-step explanation:

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

given

y = - 0.4x + 0.25 ( multiply all terms by 20 to eliminate fractions )

20y = - 8x + 5 ( add 8x to both sides )

8x + 20y = 5 ← in standard form

The value of  x from the expression is 2

<h3>Expression and equation </h3>

Given the expression

2x = 74/2 - 37


We are to calculate the value of  x from the expression

2x = 37 - 37

Since 37 - 37 = 0

2x = 0

Divide both sides by 2:

2x/2 = 0/2

x = 0

Hence the value of  x from the expression is 2

Sever21 [200]

The actual height of building is 1800 feet.

Step-by-step explanation:

Given,

Height of building in model = 3 inches

Scale used by engineer;

1 inch = 600 feet

Therefore;

Actual height of building = Height in model * Scale used

Actual height of building = 3 * 600

Actual height of building = 1800 feet

The actual height of building is 1800 feet.
