Answer:

Given: A number b minus 4.2 is less than -7.5.

Here, b is the number.

"less than" symbol is represented by '<'

"minus" means subtract.

"b minus 4.2" translated to b - 4.2

Then, our inequality becomes;


b - 4.2 < -7.5

To solve for b;

Add 4.2 both sides we get;


b -4.2 + 4.2 < -7.5 + 4.2

Simplify:


b < -3.3

Therefore, an inequality for the given word sentence is,
b - 4.2 < -7.5
