Answer:
0.27 cubic feet of mulch is remaining
Step-by-step explanation:
Quantity in the bag = 2 7/16 cubic feet of mulch
Quantity used = 8/9 of the bag in his garden
Mulch used = 8/9 of 2 7/16
= 8/9 × 39/16
= 1/9 × 39/2
= 39/18
= 2 3/8 used
Total mulch left = Total mulch in the bag - mulch used
= 2 7/16 - 2 3/8
= 39/16 - 39/18
= 702-624/288
= 78/288
= 0.27 cubic feet of mulch is remaining
2x + 3y = 6________( 1 )
-3x + 5y = 10_______( 2 )
( 1 ) × 3 ---- 6x + 9y = 18_____( 3 )
( 2 ) × 2 ---- -6x + 10y = 20_____( 4 )
y = 2 ,
In my opinion the reason 4 is incorrect
