Question:

What is the difference between tuples and lists in Python?

Inactive
Sydney R.

Lists are enclosed in brackets ( [ ] ) and their elements and size can be changed, Tuples are enclosed in parentheses ( ( ) ) and cannot be changed. Tuples can be thought of as read-only lists.

Question:

What is 12 x 3?

It may be easier to write it out like this: 12 x 3 ------- ?? Using the top number (12) work your way from right to left. So first, do 2 x 3. Since 2 x 3 = 6, we get: 12 x 3 ------- 6 But we aren't done yet, now do the same thing with the 1. Since 1 x 3 = 3, for our final answer we get: 12 x 3 ------- 36 The answer is 36

Question:

How would I solve for x in this equation? 2x + 5 = 19

The first thing you would do is subtract the 5 from both sides to get the variable by itself: 2x + 5 = 19 - 5 - 5 2x = 14 Then, to get x by itself you would divide both sides by 2: 2x/2 = 14/2 x = 7
