Answer: 11x-10y

Step-by-step explanation:

Combine like terms.

(5x+3y)-(2x-7y)+8x

3x + 8x

Remember to distribute the negative.

-(-7y) = +7y

3y +7y

Combine like terms once again.

3x+8x= 11x and 3y+7y= 10y

Answer:

The answer is 12.72 hope this helps

Step-by-step explanation:

You'll add them it's just like simple addition but you just have to know where the decimal point will be after adding

3.78

+8.94

12.72

When you are adding you start from the back with back I mean the end so when you add 8 plus 4 it's going to be 12 then you write or type the 2 and then carry the 1 and add it to the 7 which is going to be 8 then you add the 8 to the 9 which is going to be 17 that's why we have the 7 there then you carry 1 and add it to the 3 which is going to be 4 and then 4+8 is going to be;12

That's how we got the 12.72

Hope you understand

Given:

Amount saved in sale = $25

Sale price was 35% off the regular price.

To find:

The regular price of the tennis shoes.

Solution:

Let the regular price of the tennis shoes be x.

Sale price was 35% off the regular price.

[tex]Discount=\dfrac{35}{100}x[/tex]

Amount saved in sale = $25

[tex]0.35x=25[/tex]

Divide both sides by 0.35.

[tex]x=\dfrac{25}{0.35}[/tex]

[tex]x=71.42857[/tex]

[tex]x\approx 71.43[/tex]

Therefore, the regular price of the tennis shoes is $71.43.

Answer:

All of them demonstrate the distributive property, except for number 4. 1-3 all have a number on the outside of the parenthesis to distribute itself to the number and variable within the parenthesis, while #4 has a plus sign outside each pair of parenthesis, making you unable to distribute those numbers.

The correct statement is the difference of the means is 0.5.

A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary. A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.

Given:

As, from the box plot mean of boys is

= (1 x3 + 2x 7 + 3 x 6+ 4 x 2 + 5 + 6) /20

= 2.7

and, mean absolute deviation of boys

= (1.7 x 3 + 0.7 x 7 + 0.3 x 6 + 1.3 x 2 + 2.3 + 3.3)/ 20

= 1

now, from the box plot mean of girls is

= (1 x 2 + 2 x 4 + 3 x 7+ 4 x 4 + 1 x 5 + 6 x 2) /20

= 3.2

and, mean absolute deviation of girls

= (2.2 x 2+ 1.2 x 4 + 0.2 x 7+ 0.8 x 4 + 1.8 x 1+ 2.8x 2)/ 20

= 1.06

Answer:

steeper

Step-by-step explanation:

D) Vertically compressed

E) Flatter

=====================================================

Explanation:

An example would be if a = 0.5 which leads to the graph being half as tall as it used to be since 1/2 = 0.5; notice how a = 0.5 makes 0 < a < 1 true. Since the graph is squished vertically, the graph is flatter.

We don't have a reflection over the x axis since 'a' is not negative.
