Pls me asap for 10 and 11 (must show ! ) + lots of

Problem 10:
Step One: Write the expression
When a problem says some number (in this case 17) more than a variable it almost always refers to addition.  So we know that the expression's operation is addition.  We are adding 17 to our variable, n. It should look like this:
n + 17
Step Two: Replace n with a Number
Pick your favorite number and replace n with that number.  For simplicity's sake, I will choose the number 2.  So n + 17 becomes:
17 + 2
Notice how n has been replaced with our number.  Remember n could be any number, but I chose 2.
Step Three: Simplify the expression.
17 + 2 becomes 19

Problem 11:
Step One: Write the Expression
The first part of our expression is: g =
G represents the total cost of Paresh's day at the bowling alley, including all 5 games and shoe rental.
We know that to rent shoes, it cost Paresh 4 dollars.  That becomes the second part of our expression.  So now we have:
g = + 4
We also know that he played 5 games of bowling, but we don't know how much Paresh paid per game.  So to represent the cost of each individual game, we will use the variable x.  He played 5 games, so the third and final part of our expression is 5x.  So our final result is:
g = 5x + 4
