Answer:
k = 29
Step-by-step explanation:
(5k -3) + (9+k) = 180
5k-3+9+k = 180
6k + 6 = 180
6k = 180 - 6 = 174
k = 29

Answer:
Step-by-step explanation:
Let the number of jars is x.
<u>80 liters distributed, each jar has:</u>
<u>Redistribution with 4 less jars, each jar now has:</u>
<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
She prepared 8 jars at the start
