Can someone tell me if my answer for question two is wrong or not and why (brainiest) Cheryl writes 7 fewer posts than Kevin on a social media site.

Answer the questions to write an algebraic expression. Then evaluate the expression for the given value.

1. Choose a variable to represent the number of posts Kevin writes.

variable: x

2. Which operation (addition, subtraction, multiplication, or division) applies to this situation? Justify your choice.

Subtraction

Cheryl’s post is less than Kevin’s

3. Use your variable and the operation you identified to write an expression for the number of posts Cheryl wrote.

Cheryl’s number of posts: x - 7

4. If Kevin wrote 21 posts, how many did Cheryl write?

x = 21

21-7 = 14

So, Cheryl wrote 14 post on her social media site.

6e14 is the answer.

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.

16.80 times .20= 3.36

step-by-step explanation:

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely
