9514 1404 393

Answer:

  • 80 minutes
  • 34.4 km

Step-by-step explanation:

Use the second equation to substitute for d in the first equation.

  0.43t = 0.33t +8

Subtract 0.33t from both sides

  0.10t = 8

Multiply by 10

  t = 80 . . . . . . Michelle will catch Jen in 80 minutes

The distance traveled will be ...

  d = 0.43t = 0.43×80 = 34.4 . . . . km

The girls will have traveled 34.4 km when they meet.

Henry buys 6 circus tickets for himself and five friends for a total of $174. Each friend pays Henry back for his or her ticket.
Deffense [45]

Answer:

$11

Step-by-step explanation:

According to the statement, you have that 6 tickets for the price of each ticket is equal to $174 and from that, you can determine the price of each ticket:

6*P=174

P= price of each ticket

P= 174/6= 29

Now, as it says that one of Henry's friends gives him two $20 bills, that means that he gives him $40 and you have to subtract the price of the ticket from that:

40-29= 11

The answer is that if one of Henry's friends gives him two $20 bills, Henry has to return $11.
