Answer:

6 packs, 9 packs

Step-by-step explanation:

The ratio of mechanical pencil to free eraser is <em>2:4, or 1:2</em>.

So that means, for every free eraser you get, you bought the double amount of pencils.

12 free erasers x 2 = <em>24 pencils</em>

18 free erasers x 2 = <em>36 pencils</em>

And a pack of pencils contains 4.

24/4 = 6 packs

36/4 = 9 packs

How to evaluate 11+y
s344n2d4d5 [400]

Good morning ☕️

Step-by-step explanation:

11+y is an expression that contains a variable ‘y’

then its value depends on ’y’

examples :

if y = 0 → 11+y = 11+0 = 11

if y = 1 → 11+y = 11+1 = 12

if y = 2 → 11+y = 11+2 = 13

and so on.
