Answer:

n = 24

Step-by-step explanation:

16+ n/4 =22

Subtract 16 from each side

16-16+ n/4 =22-16

n/4 = 6

Multiply each side by 4

n/4*4 = 6*4

n = 24

Answer:

88%

Step-by-step explanation:

You start out by finding the number of questions she got correct

200 - 24 = 176 questions answered correctly

You then want to divide the number of question she answered correctly by the total number of questions there are.

176/200 or 176 ÷ 200 = 0.88

0.88 = 88/100 = 88%

Answer:

y=(5+3x)/5

Step-by-step explanation:

first you need to know what is slope intercept form, if not i can't help.

You need to know the property of it.

3x/5 is the slope and 5/5 is the the y-intercept.

you can try substitute some numbers like x=0, y=0.

hope help but i think you can know it from textbook.

Take y as a subject.

Step-by-step explanation:

14+8 just reverse the sign and add the 2 given numbers

Answer: x = 22

Step-by-step explanation: First, add 14 plus 8. 14 = 22 - 8. You should end up with a result of x = 22.

5 x 3 = 15

15 squared or cubed = 15 x 15 || 15 x 15 x 15

In that case, 15 times a number could not possibly be equal to 5 x 3 unless x was actually 1, which we do not know.

Answer:

NO

Step-by-step explanation:

5*3^x[tex]\neq[/tex]15x

because 3 is raised to the x power not multiplied by it, so it is not equal

Using sampling concepts, it is found that the correct option is given by:

D. Move-Em-Out because the sample is not biased.

It is when a group is taken from a population, and the data taken from the group can be taken to estimate the data for the entire population. A sample has to be representative of the population, that is, it has to avoid bias.

In this problem, the sample from Pack-and-Move was taken only from people who appeared in their commercials, meaning that the sample is biased, as these people are more likely to report high satisfaction, hence option D is correct.

Answer:

y= -7+3x

The slope of the line is 3 and the intercept on the y-axis is 7.

Step-by-step explanation:

The slope-intercept form of the equation of a line is y=mx+c, where "m" is the slope of the line and "c" is the intercept of the line on the y-axis.

To find the slope and intercept of 6x+2y=14, you should solve for "y".

From the equation we get;

2y=-6x=14 or dividing each side by 2, we'll get y=3x+7.

Answer:

Option C is the correct answer.

Step-by-step explanation:

We have been given that a and b are parallel to each with a straight angle.

If a and a are parallel, then angle suspended by a and b will be equal to each other. It is because of Alternate angle of triangle.

Let's head to the question.

According to the above statement, we have the following equation.

2x°= 4x -30°

0r, 2x° - 4° = -30°

0r, -2x° = -30

0r, 2x° = 30°

0r, x = 30°/2°

0r, x = 15°

Hence, x = 15° will show that lines a and b are parallel.

Answer: True, perpendicular lines intersect so if the lines didn’t they wouldn’t be perpendicular

Answer:

Its B

Step-by-step explanation:

The correct statement is "All real numbers that are greater than negative two".

A relationship between two expressions or values that are not equal to each other is called inequality.

Given an inequality, -5x<10

On solving, we get,

x > -2

Which is saying that, solution is all real number that is greater than -2.

Hence, All real numbers that are greater than negative two.

Part A: 50/100+3/100=x/100

Part B: Emma mistook 50/100 for 5/100 when she added it to 3/100. The correct sum would be 53/100

Answer:

Problem A:
5/10 + 3/100 = ?

Example:
Jake bought a cake. On Monday he ate 5/10 of the cake, he then put it in the fridge to store for later. On Wednesday Jake was looking through the fridge for a snack when he came across his leftover cake. His stomach was a bit small though so he only ate 3/100 of his cake. If Jake wants to finish the cake on Friday how much of the cake does he have to eat?

Problem B:
Emma added the value of 3/100 to 5/100 which is incorrect. The first graph is 5/10 or 1/2. The true value would be; 5/10 + 3/100 = 53/100. In conclusion, your answer would be 53/100 for problem B.

Usando un sistema de ecuáciones, hay que Ezequiel tiene 11 años.

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

Sandro y Ezequiel son hermanos y el producto de sus edades es igual a la edad de su padre, o sea:

xy = z

Sandro es 8 años menor que Ezequiel, o sea:

x = y - 8.

La suma de su edad y la de su padre es igual a 36, o sea:

x + z = 36.

z = 36 - x

z = 44 - y

En el primer ecuácion:

xy = z

(y - 8)y = 44 - y

y² - 7y - 44 = 0

(y - 11)(y + 4) = 0

y - 11 = 0 -> y = 11.

Ezequiel tiene 11 años.

Work Shown:

|3x+12| = 18

3x+12 = 18 or 3x+12 = -18

3x = 18-12 or 3x = -18-12

3x = 6 or 3x = -30

x = 6/3 or x = -30/3

x = 2 or x = -10

The rule used in step 2 is the idea that if |x| = k, for some positive number k, then x = k or x = -k. One equation breaks into two separate ones. From there we solve each equation for x as normal. Follow PEMDAS in reverse, undoing each operation, to isolate x.

If you're curious why the absolute value breaks into two parts, consider something like |x| = 7. This means x is 7 units away from zero on a number line. There are two possible locations where x could be: 7 and -7. This is one example showing why we get two different results. The same applies to our equation as well, just it's a bit more complicated.

The table of values are

Number of years    Account balance

1                                  $3180

2                                  $3370.80

5                           $4014.68

20                          $9621.41

The formula for calculating future value of the account balance is:

FV = P (1 + r)^n

Balance after 1 year = 3000(1.06) = $3180

Balance after 2 year = 3000(1.06^2) = $3370.80

Balance after 5 year = 3000(1.06^5) = $4014.68

Balance after 20 year = 3000(1.06^20) = $9621.41

It is given that Sylvia sells x number of bottles and Sam sells three times as many bottles as Sylvia sold to his co-workers.

So, number of bottles Sam sold is 3x.

It is also given that, number of remaining bottle Sylvia and Sam have same.

So,

24 - x = 36 - 3x

3x - x = 36 - 24

2x = 12

x = 6

Therefore, Sylvia sells 6 bottles.

Hence, this is the required solution.

The set that represents a Pythagorean triple  is B: 33, 44, 55

A Pythagorean triple consists of three positive integers such that the square of the larger one of them is equal to the sum of the squares of the other two .

Let (a, b, c) represents a Pythagorean triple where a, b, c  are positive integer and a is the larger one  then a² = b² + c²

For A: 27 ,38, 42

Let a = 42 , b= 38 ,c= 27

⇒a² = 42² = 1764

and b² + c² =  38² + 27² = 1444 + 729 = 2173

∴a² ≠ b² + c²

Thus , A: 27 ,38, 42 is not a Pythagorean triple

For B: 33 ,44, 55

Let a = 55 , b= 33 ,c= 44

⇒a² = 55² = 3025

and b² + c² =  33² + 44² = 1089 + 1936 = 3025

∴a² = b² + c²

Thus , B: 33 ,44, 55  is a Pythagorean triple

For C: 35 ,38, 42

Let a = 42 , b= 35 , c= 38

⇒a² = 42² = 1764

and b² + c² =  35² + 38² = 1225 + 1444 = 2669

∴a² ≠ b² + c²

Thus ,   C: 35 ,38, 42 is not a Pythagorean triple

For D: 68 ,72, 81

Let a = 81 , b= 68 , c= 72

⇒a² = 81² = 6561

and b² + c² =  68² + 72² = 4624 + 5184 = 9808

∴a² ≠ b² + c²

Thus ,  D: 68 ,72, 81  is not a Pythagorean triple

Therefore, Only set B: 33, 44, 55 represents a Pythagorean triple.
