Answer:
Unit rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.
In the given table shows the number of pictures taken and how much time it took.
For first camera;
Number of pictures (unit rate) per second =
pictures.
For second Camera:
Number of picture per second =
pictures.
For third Camera:
Number of picture per second =
pictures.
The camera that takes picture the fastest is, Second Camera.
(a)
As per the given statement: At Davidson's Bike rentals, it costs $29 to rent a bike for 8 hour.
⇒ unit rate per dollar =
hours
Therefore, 0.227 hours (nearest to hundredths) of bike use does a customer get per dollar.
(b)
Jessica bought 18 pounds of sugar for $10.
unit rate per dollar = 
therefore, 1.8 pounds of sugar did she get per dollar.
The greatest common factor of the two terms is 33a^3.
With the numbers 66 and 99, the greatest common factor is 33. It is the largest number that divides evenly into both.
For the variables, the most that is in common in both is a^3.
The answer is
u = -15, hope this helps!
Answer:

Step-by-step explanation:
Start by simplifying the denominator of the fraction. When multiplying exponents of the same base, you can add the exponents. This is also known as the product rule.

["a" is the base, and "x" and "y" are the exponents]
Using this we find...

When dividing exponents of the same base, you can subtract the exponents. This is also knows as the quotient rule.

Using this we find...
