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

Hope that helps!!!! Have a wonderful day!!!! : )

Suppose the average yearly salary of an individual whose final degree is a​ master's is ​$41 thousand less than twice that of an
charle [14.2K]

Answer:

The average salary of master's degree people is $ 63,000    And

The average salary of bachelor's degree people is $ 52,000  

Step-by-step explanation:

Given in question as :

Let the average salary of master's degree people = $ M       And

Let the average salary of bachelor's degree people = $ B

According to question ,

The average salary of master's degree people + The average salary of bachelor's degree people  = $115,000

Or , $ M + $ B = $ 115,000                                 ............. A

Again ,

$ M = 2 × $ B - $ 41,000                             ............... B

From eq A and eq B

(2 × $ B - $ 41,000 )   +  ( $ B ) = $ 115,000

Or, 3×$ B = 156,000

∴        B = \frac{156,000}{3} = $ 52,000

And   M = $ 115,000 - $ 52,000

∴       M = $ 63,000

Hence The average salary of master's degree people is $ 63,000    And

           The average salary of bachelor's degree people is $ 52,000   Answer

A. 5+6>7, ok

B. 6+6>10, ok
