So, by using above rule for finding average; here number of the numbers is 2 and sum of these two numbers is 25+50=75. Hence, average of 25 and 50 is: 75/2=37.5. Thus, average of 25 and 50 is 37.5.
Answer:
infinitely many solutions
Step-by-step explanation:
make both equations equal to y
so for the first one subtract 2x from both sides getting -y=-2x-1 and then multiply the entire equation by -1 and you end up with y=2x+1
and for the second one subtract 4x from both sides getting -2y=-4x-2, multiply the entire equation by -1 which gets you 2y=2x+2 and then divide the whole equation by 2 which brings you to y=2x+1
then getting rid of y and making them equal to each other gets 2x+1=2x+1 and therefore the answer is infinitely many solutions
