Noor brought 21 sheets of stickers. she gave him 1/3 of a sheet to each of the 45 students at recess. she wants to give teachers 1/1/2 sheets each. which inequality describes the number of teachers, t, noor could give the stickers to?

t is less than or equal to 4

15+3/2t is less than or equal to 21

Step-by-step explanation:

Required inequality is t ≤ 4.

Step-by-step explanation:

There are 21 sheets of stickers.

Noor gave 1/3 of a sheet to each of the 45 students.

So, she gave 1 sheet to 3 students.

Therefore, the number of sheets she gave for 45 students = .

Remaining sheets = 21 - 15 = 6

Now, the number of teachers = t

Number of sheets Noor gave to one teacher =

For t teachers, the total number of sheets given = .

Clearly, this quantity should be less than or equal to the remaining sheets 6.

Hence, the required inequality is:

3t ≤ 12

t ≤ 4

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
