Question

A number t multiplied by −4 is at least −25.

Answer 1

`t\leq 6.25` in decimal form

`t\leq (25)/(4)` in fractional form

Explanation:

-4 times a number t is greater than or equal to - 25. This is what they mean by at least.

`-4t \geq -25`

Solve for t.

`t\leq (-25)/(-4)` , we flip the inequality because we are dividing by a negative number.

`t\leq 6.25`
