1 Expert Answer
Let x and y be the two numbers. Then by assumptions we have x+y=30 and x-y=20. Hence, y=x-20 and by plugging this into the first equation we obtain x+x-20=30 or 2x=50 or x=25 and y=5
Step-by-step explanation:
So, divide 30 by 2 . That gives you 15 for x, 15 for y. Now, you have difference of six, divide by two, that equals 3.
The mean is found by adding the time it takes Greg each day and then diving by the number of days: 27+25+32=84.
84/3=28 min
it takes Greg 32 min on the third day
