You can't sorry, its only out for 4 and up.
Conan - 2010 Cheapskate Charley and the Taped-Up IPhone 3s 3-112 was released on: USA: 18 July 2013
My iPhone 3S was out of warranty and could no longer hold a charge for more than five minutes. I was considering buying a new iPhone 4S, but my AT&T equipment replacement voucher was not available until October 2012.
Apple products have very few differences in close "waves" of technology. Therefore, the 3s and 4s are nearly identical phones, but one just costs roughly 500$ more. Save yourself time and money by not upgrading until you have to.
3s + 1
135=3s +15 120=3s 40=s
28 3s
3S Facility simply means sales, services and spares
To find out how many 3s go into 140, divide 140 by 3. This gives you approximately 46.67. Since we're looking for whole 3s, you can fit 46 complete 3s into 140.
-7 = 3s - 1 +1 +1 (add 1 to both sides to get the variable alone) ___ ____ -6 = 3s __ ___ (-6 and 3s both divided by 3) 3 3 -2 = s
The easiest way is to "flip" the inequality symbol end divide by the negative number:Example:6 < 3 - 3s6 - 3 < 3 - 3s -33 < -3s Method a) Divide by negative coefficient and flip the inequality symbol3/-3 > -3s/-3-1 > s or s< -13 < -3s Method b) Full algorithm, eliminate -3s by adding 3s on both sides3 +3s < -3s + 3s3 + 3s < 03 - 3 + 3s < 0 -33s < -33s/3 < -3/3s < -1 Looks familiar? So basically if you perform the full algorithm (method b) you can understand why we flip the inequality symbol when we have to eliminate a negative coefficient but it is faster just to flip the symbol (method a)
4 3s = 4*3 = 12, which is a rational number.
