Answer 2

`5x\leq  -25`

Explanation:

The product of 5 and a number is at least –25

we convert the given statement in to inequality

product mean multiplication

Let x be the unknown number

product of 5 and a number is 5x

5x is at least -25

For word at most we use <=

for word at least we use >=

So the expression becomes 5x <= -25

`5x\leq  -25`
