2x-3y= -4 because 2x=8 since x=4 so,
8 - 3y = 20
-8. -8
-3y = 12

-3
y = -4
Answer:
40%
Step-by-step explanation:
15-9=6
6/15=2/5=40/100=40%
2/3 is 0.6. 1/2 is 0.5.
so 0.6 is less than 0.75 and it will round up to 0.5, not to 1.
so 4 2/3 will round to 4 1/2.
First, find the area of the tiles. 6 in. * 13 in. = 78 in^2.
Then divide the area of the floor by the area of the tiles.
8500 / 78 = 108 38/39
