Start by getting one of the equations in terms of one variable, in this case lets put the first equation in terms of y
2x+y=3 ---> y=3-2x
now we plug that into the second equation
5x-2y=12 ---> 5x-2(3-2x)=12
we can then multiply and simplify
5x-2(3-2x)=12 ---> 5x-6+4x=12 ---> 9x-6=12 ---> 9x=18 ---> x=2
we can now plug x=2 into an equation to solve for y
2(2)+y=3 ---> 4+y=3 ---> y=-1

Answer: 0.01708
Step-by-step explanation:
Given : If records indicate that 15 houses out of 1000 are expected to be damaged by fire in any year.
i.e. the probability that house damaged buy fire in a year : 
The formula for binomial distribution is given by :-
Now, the probability that a woman who owns 14 houses will have fire damage in 2 of them in a year (put n=14 and x=2), we get
Hence, the required probability = 0.01708
If of Saturday he drove 10 miles, then that’s 100%.
80 miles is 8 times as big as 10, which means we will multiply the 100% by 8.
Therefore the number of miles Ethan drove on Sunday is 800% the number of miles he drove on Saturday.
Answer:
Step-by-step explanation:
a + b = 331 (million)
b = 25 (million)
a + 25 = 331
a = 331 - 25
a = 306 (million).......singer a took in 306 million
