Answer:

Definition: Scaled Drawing. A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount

Example

Example #1:

Suppose a problem tells you that the length of a vehicle is drawn to scale. The scale of the drawing is 1:20.

If the length of the drawing of the vehicle on paper is 12 inches, how long is the vehicle in real life?

Set up a proportion that will look like the formula above picture

A scale drawing proportion

Do a cross product by multiplying the numerator of one fraction by the denominator of the other fraction

We get :

Length of drawing × 20 = Real length × 1

Since length of drawing = 12, we get:

12 × 20 = Real length × 1

240 inches = Real length

The real length of the vehicle is 240 inches.

2)Circumference of circle: The distance around the circular region is called its circumference. The ratio of circumference of any circle to its diameter is constant. ... Area of circle: The measure of the region enclosed inside the circle is called its area.

X+2x+7=3x-7<br> What is the answer
Tasya [4]

Answer: No solution

Step-by-step explanation:

x + 2x +7 = 3x - 7

3x + 7 = 3x - 7

3x + 7 - 7= 3x - 7 - 7

3x = 3x - 14

3x - 3x = 3x - 14 - 3x

0 = -14

The sides are not equal so there is no soulution.
