I don't know if I understand what you're saying but the likelihood of the event is as you already stated... 1/4, or I guess 25% so in other words a one in four chance of taking the bus home.
This is what you do.
x - 2y = -8
4x - 3y = -17
Add 2y to both sides on the first equation.
x = 2y - 8
4x - 3y = -17
Now substitute the x value.
4(2y - 8) -3y = -17
8y - 32 - 3y = -17
Combine like terms
5y - 32 = 17
Add 32 to both sides.
5y = 15
Divide.
y = 3
Now find x by plugging in 3 into 1 equation.
x - 2(3) = -8
x -6 = -8
Add 6 to both sides.
x = -2
So you solution is (-2, 3).
I hope this helps love! :)
Answer:
Hard to calculate first one is -1/2
Next one is 2.5/1.5 or 2 its hard to tell because of line (not clear)
Next one is -1/2 I think the numbers are small.

Answer:
72
Step-by-step explanation:
To calculate how much 20% of 360 makes we multiply 360 with 20 then divide it with 100
360 × 20 ÷ 100 = 72
