28 = 3x+4x
x = 4
3x = 12
4x = 16
12:16 = 3:4
Answer:
A and B are correct, but A is most correct.
Step-by-step explanation:
just do Pythagorean theorem and see which numbers add up to each other. if you do them for all 4 answers, you see d and c do not equal to each other. b is almost correct, and a comes out exact.
If you want 2 numbers, you have: 1+10, 2+9, 3+8, and so on. If you need 3 numbers you have 1+1+9, 1+2+8, 2+2+7, and so on.

First, find the scale factor by dividing the first building's real-life height by its model height.

Now, we'll write an equation to find the model height of the second building.

Here is an equation where
represents the real-life height of a building,
represents the scale factor, and
represents the model height of the same building.
Fill in the information we already know.

Divide both sides by
.


So, the model height of the second building is
inches.
The answer to your question is 4 and 27/ 56
