For #1:
look at the chart and write the percentages that are by the name of the food and write the percentages next to the names

For #2:
take the percentage number and divide it by 2 (because it was 50 customers out of 100%) for example if 50% of the customers picked apples then divide it by 2 and 25 customers would have gotten apples and put that number next to the name

Hope that helps :D

Add and subtract the rational expressions. 7x+5/x-1 -(8x1/x-1+2x-4/x-1) Which statements are true about the process for adding a

anzhelika [568]

Answer:

2. The denominator of the fully simplified expression will be x – 1.

4. The numerator of the fully simplified expression will be –3x + 10.

Step-by-step explanation:

Given the rational expression

$\dfrac{7x+5}{x-1} -(\dfrac{8x-1}{x-1} +\dfrac{2x-4}{x-1} )$

Let us first simplify before making our deductions.

Opening the brackets

$\dfrac{7x+5}{x-1} -(\dfrac{8x-1}{x-1} +\dfrac{2x-4}{x-1} )=\dfrac{7x+5}{x-1} -\dfrac{8x-1}{x-1} -\dfrac{2x-4}{x-1}$

Taking LCM

$=\dfrac{7x+5-(8x-1)-(2x-4)}{x-1}$

Opening the brackets and simplifying

$=\dfrac{7x+5-8x+1-2x+4}{x-1}\\\text{Collecting like terms in the numerator}\\=\dfrac{7x-8x-2x+5+1+4}{x-1}\\=\dfrac{-3x+10}{x-1}$

The following statements are therefore true:

2. The denominator of the fully simplified expression will be x – 1.

4. The numerator of the fully simplified expression will be –3x + 10.

The perimeter of a rectangular table is 680 centimeters. If the length of the table is 24

iogann1982 [59]

Answer:

The dimensions of rectangular table are length = 79 centimeters and width = 261 centimeters.

Step-by-step explanation:

Given:

The perimeter of the rectangular table is 680 centimeters.

Now, to find the dimensions:

Let, the width of rectangular table be $x$

And the length of the table be $24+3x$

Now, putting the formula of perimeter of rectangle to get the dimensions:

Perimeter = 2(length + width)

$680=2(x+(24+3x))$

$680=2(4x+24)$

$680=8x+48$

By subtracting both sides with 48 we get:

$632=8x$

Now, dividing both sides by 8 we get:

$79=x$

So, width of the table = 79 centimeters.

And, length of the table = 24+3×79

= 24+237

= 261 centimeters.

Therefore, the dimensions of rectangular table are length = 79 centimeters and width = 261 centimeters.
