Answer:
350 tickets
Step-by-step explanation:
if you do 42/350, it would equal 12%, so 350 is the total
Answer:
Yes it is rational
Step-by-step explanation:
The square root of 900 is a rational number if 900 is a perfect square. It is an irrational number if it is not a perfect square. Since 900 is a perfect square, it is rational number.
Rearrange first
2x+y=10
x+y=6
Since there is one y in both equations, you can eliminate them by subtracting.
2x+y=10
- x+y=6 subtract the two equations
-------------------
x=4
Substitute x in one of them
2(4)+y=10
y=10-8
y=2
Answer:
The value of x is -3
Step-by-step explanation:
∵ y ∝ x ⇒ y = kx
∵ y = 4 when x = -2
∴ 4 = -2 k ⇒ k = -2
∴ y = -2 x
∵ y = 6
∴ 6 = -2 x
∴ x = 6/-2 = -3
Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}
