He runs an average of 4 miles a day
Answer:
The number is 91
Step-by-step explanation:
Let x be the ones place digit and y be the tens place digit,
Then the number would be 10y + x,
We have,
y - x = 8
Possible values of y and x = { (8, 0), (9, 1) }
∵ 0 is not the digit of the number,
Hence, y = 9 and x = 1
Therefore, required number = 10(9) + 1 = 90 + 1 = 91
The doctor would have 72 patients each week. Meaning 3744 each year.
2x - 10 = 30
2x = 40
x = 20
I got 8/3 because 4/8 would simplify to 1/2 and the line would be flatter
