sydney increased her collection of coins by six.

benjamin lost six of his stickers.

six servings of dinner were decreased by a number.

westville has 6 fewer schools than eastville.

Naomi gives some of her six pencils away

Six servings of dinner were decreased by a number

Gabrielle decreased her 6-minute mile by an unknown amount of time

Step-by-step explanation:

Verify each case

Part 1) Naomi gives some of her six pencils away

Let

x > some of Naomi's six pencils

The algebraic expression that represent this situation is

6-x

therefore

This situation can represent the given expression

Part 2) Sydney increased her collection of coins by six

Let

x > the number of coins in Sydney's collection

The algebraic expression that represent this situation is

x+6

therefore

This situation cannot represent the given expression

Part 3) Benjamin lost six of his stickers

Let

x > the number of stickers that Benjamin has

The algebraic expression that represent this situation is

x-6

therefore

This situation cannot represent the given expression

Part 4) Six servings of dinner were decreased by a number

Let

x > the number  

The algebraic expression that represent this situation is

6-x

therefore

This situation can represent the given expression

Part 5) Westville has 6 fewer schools than Eastville

Let

x > the number of schools Eastville has

The algebraic expression that represent the number of schools  Westville has is

x-6

therefore

This situation cannot represent the given expression

Part 6) Gabrielle decreased her 6-minute mile by an unknown amount of time

Let

x > an unknown amount of time  

The algebraic expression that represent this situation is

6-x

therefore

This situation can represent the given expression
