Estimate 285 as 300 and 11 as 10 so
we have 300 / 10 = 30
Its C
Hello! 36 does not belong in the pattern. The pattern is multiply by 2, but 36 doesn’t belong, because half of it is 18 and 18 is not an option. The other numbers go together to make that pattern of multiplying by 2. The answer is 36.
2x+y-10=0
2x+y=10 ------------------->(1)
x-y-5=0
x-y=5------------------------>(2)
(1)+(2); 3x=15
x= 5
(x=5) substitute in (1); y=0
x ≥ 11, x ≤ 8.
The equal then part means closed circle.
If we graph this there's a gap from 8 to 11 so there isn't shading in between.
Option 4 is correct.
