Answer:

$10-5x=3\left(x-4\right)-2\left(x+7\right)$

$3\left(x-4\right)-2\left(x+7\right)$

combine like terms:-

$=3x-12-2x-14$

$3x-2x=x$

$=x-12-14$

Subtract -12 -14

$=x-26$

$10-5x=x-26$

Subtract 10 from both sides:-

$-5x=x-36$

Now, subtract x from both sides:-

$-5x-x=x-36-x$

$-6x=-36$

Divide both sides by -6:-

$\frac{-6x}{-6}=\frac{-36}{-6}$

$x=6$

Answer:

x=6

Step-by-step explanation:

10-5x=3(x-4)-2(x+7)

Distribute

10-5x=3x-12-2x14

Combine like terms

10-5x = x-26

add 5x to each side

10-5x+5x = x+5x-26

10 = 6x-26

Add 26 to each side

10+26 = 6x-26+26

36 = 6x

Divide by 6

36/6 = 6x/6

6 =x

All pieces of pizza must be square with none left over. What is the side length of the largest square pieces into which Juanita

Ber [7]

Answer:

6 in

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Juanita and samuel are planning a pizza party. they order a rectangle sheet pizza that measures 21 inches by 36 inches.? they tell the pizza maker not to cut it because they want to cut it themselves. All pieces of pizza must be square with none left over. what is the side length of the largest square pieces into which juanita and samuel can cut the pizza?

First we need to calculate the area of the rectangular pizza.

Area of a rectangle = Length × Breadth

Area of the rectangular pizza= 21×36

Area of the rectangular pizza = 756in²

Next is to equate the area of the rectangle to the area of a square.

Area of a square = L²

Therefore L² = 756

L = √756

L = √36×21

L = √36×√21

L = 6√21

This means that the length if the largest square they can cut is 6in (ignoring the irrational part of the length gotten)

The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 7% of his customer

Mrrafil [7]

Using the binomial distribution, it is found that there is a 0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

7% of his customers buy a magazine, hence p = 0.07.

A sample of 14 customers is taken, hence n = 14.

The probability that exactly 4 out of the first 14 customers buy a magazine is P(X = 4), hence:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 4) = C_{14,4}.(0.07)^{4}.(0.93)^{10} = 0.0116$

0.0116 = 1.16% probability that exactly 4 out of the first 14 customers buy a magazine.

A square park has an area of 6561 square meters. If you walk around the park what is the distance that you would have walked?

jekas [21]

The area of a square is the side of the square squared or A= s^2 (s meaning side of the square)
Perimeter or the 4 sides is P= 4 x s
Since the area is 6561, plug that into the area formula so you get 6561= s^2
Next, take the square root of both sides of the equation because that is the opposite of squaring a number)
When you do that you get s = 81
Now that you know s, plug it into the Perimeter formula P= 4 x 81
The perimeter or distance around the park is 324 meters.
