Question

Number minus seven is at most fifteen, or four times the number is at least twenty-four. How do you write an inequality for this situation and solve?

Answer 1

`x<=22 or x>=6`

Explanation:

let's fix x as the unknown number, then

`x-7<=15 or 4x>=24`

that is solved by:

`x<=22 or x>=6`

This can also be written as `6<=x<=22` or in interval form `[6,22]`
