Nine increased by a number fourteen decreased by a number seven less than a number the product of nine and a number thirty-two divided by a number five more than twice a number the product of a number and six seven divided by twice a number three times a number decreased by eleven

Step-by-step explanation:

Write each phrase as an algebraic expression.

Let the unknown number = x

1. Nine increased by a number

= 9 + x

2. Fourteen decreased by a number

= 14 - x

3. Seven less than a number

= x - 7

4 The product of nine and a number

= 9 * x

= 9x

5. Thirty-two divided by a number

= 32 / y

6. Five more than twice a number

= 2x + 5

7. The product of a number and six

= x * 6

= 6x

8. Seven divided by twice a number

= 7 / 2x

9. Three times a number decreased by eleven

= 3x - 11
