2.5 kilometres is 2500 meters as 1km is 1000m
2500-2050 = 450m
as david is the one that rode 2.5 kilometres he rode further by 450 meters
Answer:
3rd choice
Step-by-step explanation:
The answer is the 3rd choice.
x cannot be 3 and 5 at the same time.
x = 3
x = 5
Subtract the first equation from the second equation.
x - x = 5 - 3
0 = 2
Since 0 = 2 is a false statement, there is no solution.
Answer: 3rd choice
For short you call this scientific notation.
FIRST
Count how many time you need to move the decimal over to make your single digit more then 1 and less then 10. So we will erase the 0's as we go along.
167000,000,000,000
So in this case we want to make the single digit 1.67 so it can be greater then 1 and less then 10
So now we see how many times we need to move the decimal and when you cant see the decimal just imagine it at the very end of the problem
167000,000,000,000
(For the mods out there I copied and pasted the bold number so i didn't have to take a while to retype the whole number. Thanks.)
SO NOW I get 14 because that's how many spots the decimal moved over.
Now since we need to right it in SN we need to write out this
X*10^X
The exponent X stands for how many times we moved the decimal over. I got 14 so we have that exponent
X*10^14
NOW We need to fiqure out X.... X was just the number we made greater then one and less then 0.
So thats 1.67
So we get
1.67*10^14

Answer:
Jose's solution is not correct, the auditorium has 
rows
Step-by-step explanation:
we have
where
f(x)------> is the total number of seats in an auditorium
x----> represents the number of rows
How many rows are there in the auditorium if it has a total of 416 seats?
Find the value of x for f(x)=416 seats
substitute the value of f(x) in the equation
Using a graphing calculator
The values of x are 
The solution is
x=16 rows because the number of rows can not be a negative number
