So if there are twenty children and 6 have an average age of five, you could say their total age together is 30 years. The others (20-6) have an age of 8.
30+ (20-6)*8 = total age of every child at the library. From there divide by the number of children.
Answer:
-12
Step-by-step explanation:
Because the numbers are negative, the "bigger" they get, the negative sign actually makes them smaller. So -12 is the closest to zero, making it bigger than -15.
Hello there!
Do solve for this, we actually just have to do one thing since our number is the same - subtract the exponents.
When you divide by exponents, you are subtracting them.
For example;
Subtract the exponents.
is your answer for this example.
Let's apply this to our current expression.
Subtract the exponents.
is your simplified expression with exponents.
I hope this helps!

To find the slope of the graph you pick any piece of the line, and divide the vertical difference between its ends by the horizontal difference between its ends. If the graph is distance versus time then the slope represents the speed.
