One third of a number t is less than or equal to 5

t ≤ 15

Step-by-step explanation:

The number is t, and 1/3 of that number would be t

So:

t ≤ 5

If we solve for t we get out answer.

t = 5  Divide each side by

When you divide by a fraction you take it's inverse and multiply,

so becomes which is the same as 3.  

Now we have t = 5*3

t = 15

So t must be less than or equal to 15.

t ≤ 15

You can check your answer by choosing a number greater than 15 and less than 15.

Let's choose 12 and 18.

t ≤ 5                                                     t ≤ 5

(12) ≤ 5                                                 (18) ≤ 5

4 ≤ 5                                                        6 ≤ 5

Yes!                                                           No!

So our answer is correct.

x=6 and x=3

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
