Answer fast which situations can represent the expression 6 - x ? check all that apply.

naomi gives some of her six pencils away.

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.

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

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

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
