Question

I need help with my algebrayou need to write the sentence as a inequality:the difference of a number and 7 is at least 25

Answer 1

When they refer to a number it can be expressed as x.

The difference of a number and 7 can be expressed as x-7.

And when they use the expression at least, it means greater than or equal to, that means that the sentence written as an inequality is:

`x-7\ge25`
