Question

The difference of twice a number and 5

 is at most −16.

.

Answer 1

Hi Reyna,

Difference implies subtraction, at most implies less than or equal to, so:

2n-5<= -16

n is the number you seek.

If the question was just to express algebraically, that is the answer. If you need to simplify the inequality, add 5 on both sides:

2n<= -11

Divide by 2 on both sides:

n<= -11/2 or

n<= -5.5

I hope this helps.
