Answer:
The Answer is C.
Step-by-step explanation:
Well you add the total of championships. 15+7+7+6+4+2=41
The ratio is 6:41
This means that Australia won 6 of the 41 championships.
X = 16
x = - 16
You could do it this way
x^2 - 256 = 0
(x - 16)(x + 16) = 0
x - 16 = 0
x = 16
x + 16 = 0
x = - 16
Answer: x ≤ -5.5
reason:
first, multiply 4x and -2 by 1/2 and 6x and 9 by -2/3.
this makes the equation 2x-1-4x-6 ≤ 4
combine like terms to make it -2x-7 ≤ 4
add 7 to both sides to get -2x ≤ 11
divide both sides by -2 and get x ≤ -5.5
300 because it's not at 50 or above 50 yet
