a_sh-v [17]

In unit of batches over days, let r be the planned rate and R be the actual increased rate. The difference between R and r is described as 10 shirts per day.

R-r=10

                        Rate                  Time                  Batches

Planned              r                          8                           1

Actual                 R                         7                            1


\left[\begin{array}{c}r=1/8&R=1/7&R-r=HowManyBatchesInTenShirts\end{array}\right]

1/7-1/8, the number of batches equivalent to 10 shirts.

(1/56)*Batches=10*Shirts

OneBatch=560*Shirts

Hope This Helps!!!

tigry1 [53]

Answer:

<u>The three equations:</u>

  • y = 15x, wolf
  • y = 10x + 15, you
  • y = 5x + 20, friend

<u>Compare the equations with wolf and you and with wolf and your friend:</u>

  • 15x = 10x + 15
  • 5x = 15
  • x = 3 seconds

It will take 3 seconds before you are caught by the wolf

  • 15x = 5x + 20
  • 10x = 20
  • x = 2 seconds

It will take 2 seconds before your friend is caught by the wolf, he will be caught a second before you.
