The linear combination method is applied to a system of
equations:
1. (4x+10y = 12)
(10x + 25y = 30) -
2. 2x + 5y = 6
-2x - 5y =-6
31. 0 = 0

step-by-step explanation:

compare

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
