13). z = ( 9/13)(C)

Solve for C:

Step 1: flip Equation:

9/13 c = z

Step 2: Divide both sides by 9/13

9/13 c/9/13 = z/9/13

C = 13z/9

Answer: Letter Choice, (D), C = 13z/9

12.). Let " h" be the number of hikes:

Expense of First Club:

C * h = 20 + 5h

Expense of Second CluB:

C * h = 7h

20 + 5h < 7h

20 < 2h

h > 10 hikes

Answer: The First Club is Less Expensive, If it is more than Ten Hikes.

14.). Co-Efficient of Friction Formula:

ma = F - mw

+ mw + mw (cancel out +mw)

Mw + ma = F - ma

-ma -ma (Cancel out -ma)

Divide: Both sides by w:

Mw/w = F - ma/w

Therefore, Answer: Letter Choice, (D), M = F - ma/w
