We know that the length of the classroom is 2.4 times its width, so the length of the model is 2.4w inches.
We can set up the proportion: 2.4w / w = 42 / x
Simplifying the proportion, we have: 2.4 = 42 / x
To solve for x (the width of the model), we can cross-multiply: 2.4x = 42
Dividing both sides by 2.4, we find: x = 42 / 2.4
Calculating this, we get x ≈ 17.5
Therefore, the width of the model should be approximately 17.5 in.
The correct answer is 17.5 in.

x = 7
x = 7
x = 13
x = 13
x = 30
x = 30
x = 0
x = 0
So, x - 3 + 3 = 10 + 3
This simplifies to x = 13.
Therefore, the solution to the equation x - 3 = 10 is x = 13.
The correct answer is x = 13.
