zvonat [6]

Answer:

  • 8 jars

Step-by-step explanation:

Let the number of jars is x.

<u>80 liters distributed, each jar has:</u>

  • 80/x

<u>Redistribution with 4 less jars, each jar now has:</u>

  • 80/(x - 4)

<u>Each jar has now twice the amount:</u>

  • 80/x*2 = 80/(x - 4)
  • 2/x = 1/(x - 4)
  • 2(x - 4) = x
  • 2x - 8 = x
  • x = 8

malfutka [58]

Answer:

a = 5

Step-by-step explanation:

a/4 = 15/12

We can use cross products to solve

a* 12 = 4*15

12a = 60

Divide each side by 12

12a/12 = 60/12

a =5
