Answer:

  $110

Step-by-step explanation:

Let a, b, and c represent the earnings of Alan, Bob, and Charles. The problem statement tells us ...

  a + b + c = 480 . . . . . . the combined total of their earnings

  -a + b = 40 . . . . . . . . . . Bob earned 40 more than Alan

  2a - c = 0 . . . . . . . . . . . Charles earned twice as much as Alan

Adding the first and third equations, we get ...

  (a + b + c) + (2a - c) = (480) + (0)

  3a + b = 480

Subtracting the second equation gives ...

  (3a +b) - (-a +b) = (480) -(40)

  4a = 440 . . . . . . . . simplify

  a = 110 . . . . . . . . . . divide by the coefficient of a

Alan earned $110.

_____

<em>Check</em>

Bob earned $40 more, so $150. Charles earned twice as much, so $220.

The total is then $110 +150 +220 = $480 . . . . as required

Watch day about 75,000 people visit Paris, France. Use commutative property to write two equivalent expressions that could be us
Studentka2010 [4]

Answer:

5\times 75,000 and 75,000\times 5

Step-by-step explanation:

We have been given that about 75,000 people visit Paris, France. We are asked to write two equivalent expressions that could be used to find the number of people that visits over a 5- day period .

To find the number of people over a 5-day period, we will multiply 75,000 people by 5 as:

\text{Number of people that visits over a 5-day period}=75,000\times 5

Commutative property of multiplication states that we can multiply numbers in any order.

Upon switching the order while multiplying, we will get:

\text{Number of people that visits over a 5-day period}=5\times 75,000

Therefore, our required equivalent expressions would be 5\times 75,000 and 75,000\times 5.
