Answer: The factors of 14 are 14, 7, 2, 1.

             The factors of 55 are 55, 11, 5, 1.

The common factors of 14 and 55 are 1, intersecting the two sets above.

In the intersection factors of 14 factors of 55 the greatest element is 1.

Therefore, the greatest common factor of 14 and 55 is 1.

Step-by-step explanation:

The greatest common factor of 14 and 55 is 1.

To find the greatest common factor of 14 and 55.

First write the factor of 14.

14 × 1 = 14, 7 × 2 = 14, 2 × 7 = 14, 1 × 14 = 14.

Which are 14, 7, 2 and 1.

Now, write the factor of 55.

55 × 1 = 55, 11 × 5 = 55, 5 × 11 = 55, 1 × 55 = 55

Which are 55, 11, 5 and 1

Therefore, the common factor of 14 and 55 is 1.

Answer:

Kay sold 6 boxes and Ayan sold 19 boxes

Step-by-step explanation:

Let x = number of boxes Kay sells

y = number of boxes Ayan sells

Then the equations will be:

[tex]x+y = 25\\x = y-13[/tex]

We can solve the system by using substitution method

Putting x = y-13 in equation 1

[tex]y-13+y = 25\\2y -13 = 25\\2y = 25+13\\2y = 38[/tex]

Dividing both sides by 2

[tex]\frac{2y}{2} = \frac{38}{2}\\y = 19[/tex]

Putting y = 19 in equation 2

[tex]x = y-13\\x = 19-13\\x = 6[/tex]

Hence,

Kay sold 6 boxes and Ayan sold 19 boxes

Answer:

y = x + 2.5 or y = x + 5/2

Step-by-step explanation:

Multiply both sides by 2 so that they are not fractions anymore.

[tex](2)\frac{2y}{2} = \frac{2x}{2} + \frac{5}{2} (2)\\[/tex] This gives you...

2y = 2x + 5 (divide both sides by 2 to get the y alone.)

y = x + 2.5

Step-by-step explanation:

5-1=4×5=20 that's why

Answer:

x = 20

Step-by-step explanation:

[tex]\frac{x}{5} + 1 = 5[/tex]

isolate the [tex]\frac{x}{5}[/tex] by subtracting 1 from both sides

[tex]\frac{x}{5} + 1 -1 = 5-1[/tex]

[tex]\frac{x}{5} = 4[/tex]

then isolate the x by multiplying both sides by 5

[tex]\frac{x}{5} * 5 = 4 * 5[/tex]

[tex]x = 4 *5 = 20[/tex]

so

[tex]x = 20[/tex]

The two clowns charge the same amount of money at 16.66 hours.

Payment for work based on hours worked (or sometimes per day or per amount of work done).

Here, let the duration of birthday party be x hours.

For Clown A,

Initial fee = $ 105

Additional charge = $ 9 per hour

Total amount of clown A = $ (9x + 105)   ...........(i)

For Clown B,

Initial fee = $ 155

Additional charge = $ 6 per hour

Total amount of clown B = $ (6x + 155)   ...........(i)

Now, according to question

9x + 105 = 6x + 155

9x - 6x = 155 - 105

3x = 50

x = 50/3

x = 16.66 hours

Thus, the two clowns charge the same amount of money at 16.66 hours.

Answer:

I think the answer is 252 liters a minute.

Step-by-step explanation:

I got 252 liters a minute because I had to first put 4 1/5 as a fraction and it was 21/5. In ever minute there are 60 seconds. I then multiplied 21/5 times 60 to get me to 252 liters. To double check your work you have to divide 252 by 60. When you divide 252 by 60 you would get 4.2 which reduces to 4 1/5 which makes 252 liters per minute the right answer. Hope this helps.

Answer:

Let's define the symbols:

x <  y

means that x is strictly less than y.

x ≤ y

means that x is less than or equal to y.

(both of these signs can be in the other direction, take that in mind).

A) " a is always less than another number b"

Here we should have:

a < b.

a is always less than the other number b.

This is not in the options, so i suppose that there is a mistake in the question.

B) The expression "above" is not shown here, so i will just writhe the correspondent expression for each option, and you can see which one matches with the expression above.

a) "The product between 3 and a number is no less than 9"

3*n ≥ 9.

b) "The product between 3 and a number is greater than 9."

3*n > 9

c) "The product between 3 and a number is no more than 9"

3*n ≤ 9

d) "The product between 3 and a number is less than 9"

Step-by-step explanation:

m<2 = 50 degrees

because <1 and <2 are alternate interior angles so they are congruent

Answer:

Step-by-step explanation:

The sales tax is ≈ 12.74

The total of $93 - (12.74 + 73.89)  = 6.37

$6.37 is approximatley 20%

The description of the service they received is

They left a 20% tip, so the service was probably above average.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

let the amount of tax be x.

So, 100% of x = 73.89 x 5.8%

x = 428.562/100

x= 4.285

Now, the tip amount would be

= 93 - 73.89 4.28

= $14.83

Now, the amount of tip in percent is

73.89 / 100 = 14.83 / x

x = 14.83 /0.7389

x= 20.07

x= 20%
