What is equivelent to
4d+6+2d

Answers

The value of the equation 4d + 6 + 2d is A = 6 + 6d

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 4d + 6 + 2d be equation (1)

On simplifying the equation , we get

A = 4d + 2d + 6

A = 6d + 6

A = 6 ( d + 1 )

Therefore , the value of A is 6d + 6

Hence , the value of the equation is A = 6d + 6

We can add like terms. Like terms are when the variables are alike, so you can add them to get a simpler form of your expression.equation.
4d and 2d are like terms, therefore, we can add them.

6d+6 is what we are left with.

Our final answer: 6d+6 is equivalent to 4d+6+2d

candice bought 3 shirts. each shirt cost the same amount and was discounted by $3.66. candice paid a total of $62.31 before tax.how much did each shirt cost before the discount?

Answers

discount per shirt=3.66

so therefor
3x=3 times original cost per shirt
discount means minus
3x-3(3.66) since 3 discounts since 1 discount per shirt

she paid 62.31
after discount so
3x-3(3.66)=62.31
solve for x which is cost per shirt orinilally

3x-3(3.66)=62.31
divde both sides by 3
x-3.66=20.77

add 3.66 to both sides
x=24.43
cost per shirt was $24.43

A recipe for one batch of cookies uses 5 cups of flour and 2 teaspoons of vanilla. If you use 20 cups of flour how many cups of vanilla should i use

Answers

The cup of vanilla to be used to prepare a recipe for the 4 batches of cookies is 0.1667 cups of vanilla.

Given that:

1 batch of the cookies = 5 cups of fours + 2 teaspoons of Vallina

If 20 cups of flours are used and we know a cookie require just 5 cups, then:

the number of cookies to be made from 20 cups of flours is:

= (20 cups of flours × number of cookies)/5 cups of flour
= 4 cookies

Since there are 4 cookies to be made, then the total number of teaspoons to be used for the 4 cookies is;

= 2 × 4 cookies
= 8 cookies

Thus, 20 cups of flour and 8 teaspoons of vanilla are required to make four batches of cookies.

But, we are to leave our answers in cups of vanilla. Let, the unknown number of cups of vanilla be (x)

In a cup, there are 48 teaspoons
In (x) cup now, there are 8 teaspoons.

1 × 8 = 48 × (x)

(x) = (1 ×8)/48

(x) = 8/48

(x) = 0.1667 cups of vanilla.

Therefore, we can conclude that the cups of vanilla to be used are 0.1667 cups.

PLEASE HURRYA 5 inch × 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches larger than the width and length of the photograph. Which expression represents the perimeter of the frame?

Answers

Answer:

48in

Step-by-step explanation:

We know that the photograph is

Width photo = 5in

Lenght photo = 7in

The length and width of the frame are 2x inches larger than the width and frame of the photograph so:

Width frame = 5in x 2 = 10 in

Lenght frame = 7in x 2 = 14 in

The perimeter is the distance around a two-dimensional shape. Then, the perimeter of the frame is:

Perimeter = 10 in + 14 in + 10 in + 14 in = 48in
