The length of a rectangle is 4ft longer than it’s width. If the perimeter of the rectangle is 68ft, find it’s length and width.

Answers

Answer:

Represent the length and width by L and W. Then L = W + 4.

Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).

Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.

The dimensions of the rectangle are 15 by 19 feet.

Reading the expression:

We're given the sigma notation of a series.

The variable k is the "index of notation"

The expression can be read as the sum of (2k- 11) as k goes from 1 to 5.

The difference between 4 times a number and 6 is 18.

n = 24
n = 6
n

4
n = 4

Answers

Answer:

6

Step-by-step explanation:

Let the number be " n ".

4 times a number,

= 4n

The difference between 4 times a number and 6

= 4n - 6

The difference between 4 times a number and 6 is 18,

4n - 6 = 18

4n = 18 + 6

4n = 24

n = 24 / 4

n = 6

The value of "n" that satisfies the equation is n = 6.

Option B is the correct answer.

We have,

To solve the equation "The difference between 4 times a number and 6 is 18," let's define the unknown number as "n."

The difference between 4 times the number and 6 can be expressed as "4n - 6."

According to the given equation, this expression equals 18:

4n - 6 = 18

To solve for "n," we will isolate the variable by performing the necessary algebraic steps:

Add 6 to both sides of the equation:

4n - 6 + 6 = 18 + 6

This simplifies to:

4n = 24

Next, divide both sides of the equation by 4 to isolate "n":

(4n) / 4 = 24 / 4

This simplifies to:

n = 6

Therefore,

The value of "n" that satisfies the equation is n = 6.

A ice cream cone cost $3 plus an additional $0.50 per scoop. James pald a total of $4.50, which equation below
models this situation.
4.50 + 0.50x = 3
0.50x + 3 = 4.50
0.50x = 7.50
3x + 0.50 = 4.50

Answers

Answer:

B: 0.50x + 3 = 4.50

Step-by-step explanation:

James needed an additional 3 scoops so the x would have to be on $0.50. the $3 is what the cone cost so it has to be with the scoop price. $4.50 is the total price of the ice cream so that would be on the other side of the equal sign, resulting in 0.50x + 3 = 4.50
