Answer:

The number of paper clips that Crystal has is 3 and the number of paper clips that Gayle has is 14

Step-by-step explanation:

Let

x----> the number of paper clips that Crystal has

y ---> the number of paper clips that Gayle has

we know that

$y=x+11$ ----> equation A

$x=42/y$ ----> equation B

substitute equation A in equation B

$x=\frac{42}{x+11} \\ \\x^{2} +11x=42\\ \\x^{2} +11x-42=0$

Solve the quadratic equation by graphing

The solution is $x=3\ paper\ clips$

see the attached figure

Find the value of y

$y=3+11=14\ paper\ clips$

therefore

The number of paper clips that Crystal has is 3

The number of paper clips that Gayle has is 14

Luis is a professional musician.He needs to

Deffense [45]

Step-by-step explanation:

The following prices for the same make and model used guitar for his work are :

$699.20,$700.30,$680.50,$700.30, and $800.25.

Mean of ungrouped data = sum of observations/total no of observations

$\text{Mean}=\dfrac{699.20+700.30+680.50+700.30+800.25}{5}\\\\\text{Mean}=\$716.11$

For median, arrange the given data in ascending order.

$680.50, $699.20, $700.30, $700.30, $800.25

Median = middle value

Median = $700.30

The value that comes most often is called mode.

$700.30 comes two times. So, mode is $700.30

Hence, Mean = $716.11, median = $700.30 and mode = $700.30

Equivalent fractions for 9/11, 15/17, and 2/3 using the least common denominator.

TiliK225 [7]

The (small) challenge here is to determine what the LCD is. Since 11, 17 and 3 are all prime, we find the LCD by multiplying them together: 561.

Then 9/11= 459/561; 15/17 = 495/561; and 2/3 = 375/561.
