2x+y=12
3x+2y=38
you have to use substitution to solve this problem

Can someone me i’m confused. will give brainliest and a whole bunch of points

You were told that the amount of time lapsed between consecutive trades on the new york stock exchange followed a normal distribution with a mean of 15 seconds. you were also told that the probability that the time lapsed between two consecutive trades to fall between 16 to 17 seconds was 13%. the probability that the time lapsed between two consecutive trades would fall below 13 seconds was 7%. what is the probability that the time lapsed between two consecutive trades will be between 14 and 15 seconds?

What is the result of adding the system of equations? 2x+y=4 3x-y=6
