You need to figure out how many ways you can roll a sum of 9.
3 and 6, 4 and 5, 5 and 4, and 6 and 3. That's 4/36, or a 1/9 chance.
Alex has a 1/6 chance. Therefore, Alex is more likely to win.

Answer:
(x, y) = (-1, -16) or (3, 0)
Step-by-step explanation:
Perhaps you want to solve the system of equations ...
- y = x^2 +2x -15
- y -4x = -12
Substituting the first expression for y into the second equation gives ...
x^2 +2x -15 -4x = -12
x^2 -2x -3 = 0 . . . . . . . . add 12
(x -3)(x +1) = 0 . . . . . . . factor
Solutions are the values of x that make the factors zero: x = 3, x = -1.
The corresponding values of y are ...
y = -12 +4x
y = -12 +4{-1, 3} = -12 +{-4, 12} = {-16, 0}
The solutions to the system are ...
(x, y) = (-1, -16) or (3, 0)
Answer:
should also be 40
Step-by-step explanation:
the measure of angle 1 is equivelent to angle two, since they both lie ont he same line.
(300) (30,000) = 9 x 10m
9,000,000 = 90m
divide by 90
100,000 = m
