The sum of one third of a number and 2 1/3 is 9 find number
hammer [34]

Answer:

  20

Step-by-step explanation:

The given relation can be written as the 2-step linear equation ...

  (1/3)n +2 1/3 = 9

  n +7 = 27 . . . . . . . . . step 1: multipy by 3 (makes the coefficient = 1)

  n = 20 . . . . . . . . . . . step 2: subtract 7 (separates variable from constant)

The number is 20.

_____

<em>Additional comment</em>

Usually it is convenient to do the two steps in the opposite order: get the variable term by itself, then make its coefficient 1. Here, we chose the order we did because it eliminated fractions from the problem, which is often a step you'd like to do first.

Answer:

The answer to your question is   a² + 9a + 20

Step-by-step explanation:

               10a² + 3a + 25 - (9a² - 6a + 5)

- Remove parentheses changing the sign of the second polynomial

               10a² + 3a + 25 - 9a² + 6a - 5

- Group like terms

               (10a² - 9a²) + (3a + 6a) + (25 - 5)

- Simplify and result

                a² + 9a + 20
