Answer:
-70x + 21
Step-by-step explanation:
1-8 = -7.
-7(10x-3)
Distribute, you get -70x + 21.
-52 (x - 97) = x + 39
-52x + 5,044 = x + 39
+52x +52x
5,044 = 53x + 39
-39 - 39
5,005 = 53x
____ ____
53x 53x
94.43 = x
The sentence describing the scale of the model is 1 m represents 40m.
Given,
The length of the ship = 120 m
A scale model of the ship is made.
The length of the model = 3 m
We have to find that, 1m in model represents how much meter of the original.
Scale model;
A physical model that is geometrically similar to an object is called a scale model (known as the prototype). Scale models may be larger than small prototypes like anatomical structures or subatomic particles, but they are often smaller than huge prototypes like cars, buildings, or people.
Here,
Original ; scale model
120 ; 3
That is,
120/3 = 40
Therefore,
1 meter in scale model represents 40 m of the original ship.
