Question

Explain how to write and evaluate an algebraic expression.

thirteen less than the quotient of forty and a number; evaluate when n = 2.

Answer 1

40. 40
------ -13 ------ -13. 20-13. 7
N 2
You would write this this by just looking at the key terms like for example (13 less than) which means it's being subtracted. And (quotient of 40 and a number) means that it's going to be a fraction with 40 at the top and n on the bottom. It's really simple once you get practice hope this helps :)

Answer 2

The value of the given expression when (n = 2) is 7 and this can be determined by using the arithmetic operations.

Given :

Thirteen less than the quotient of forty and a number.

The following steps can be used in order to evaluate the given expression when (n = 2):

• Step 1 - The arithmetic operations can be used in order to evaluate the given expression.

• Step 2 - Write down the mathematical expression using the given data.

                       $y = \dfrac{40}{n}-13$

                   where 'n' is any number and 'y' is the value of the expression.

• Step 3 - So, the value of 'y' when (n = 2) is calculated as:

                       $y = \dfrac{40}{2}-13$

• Step 4 - Simplify the above expression.

                 $y = 20 - 13$

                 $y = 7$

The value of the given expression when (n = 2) is 7.
