Answer:
x=9
y=3
Step-by-step explanation:
since all three sides of an equlateral triangle are equal:
3x+y=30 then y=30-3x
4x-2y=30
4x-2(30-3x)=30
4x-60+6x=30
10x=90
x=9
3x+y=4x-2y
x=3y
y=3
3/6 of a minute because an hour is much longer
Well if the probability of getting a tail is 0.31 then the probability of getting a head must be 0.69 because 0.31 is much like 31% and the last 0.69 makes 69% resulting in the total 100% chance when combining the outcome chances seeing as a coin only has 2 sides.
