Sorry sir... but the screen is blurry. ; u ;
the last digit is the ones place, if it is 5 or higher you would round up
under 5 you round down
so to the nearest 10 the number would be 67910
Answer: 19 years old
Explanation: We can use the equation 3x+48=105
3 is the growth rate/slope, 48 is the initial height/the constant, and x is the age
Subtracting 48 from both sides leaves us with 3x=57.
Dividing both sides by 3 gives us x=19.
