No, because the perimeter of a rectangle is 2(x+y). Justin added the sides. Then he should have multiplied by 2 but he didn't so Justin is incorrect.
Hope this helps plz mark brainliest :D
Answer:
No, his answer should have been 6x+2
Step-by-step explanation:
The equation for perimeter is 2L+ 2W=P
so 2 (2x-3) + 2 (x+4) = 6x+2
is 15(x+10) largger than 360
Answer:
No it's not

(5x+3y)-(2x-7y)+8x please help
Answer:
A I soo sorry but I really can't solve this I have not learned it yet
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

what is 3.78 plus 8.94
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

1. A sticker costs 25 cents. How many dollars is that?
2. A pen costs 1.50 dollars. How many cents is that?
3. How many cents are in one dollar?
4. How many dollars are in one cent?
Plz help!!!
Answer:
1: 1/4 dollars or .25 dollars or 25%
2: 150 cents
3: 100 cents
4: 1/100 dollars, or 0.01 dollars, or 1%
Step-by-step explanation:
The answers to the given problems are found by converting the units as $0.25, 150 cents, 100 cents and $0.01.
What is a Measurement unit?A measurement unit is a unit to measure certain quantities. For example, the mass can be measured in kilograms, length can be measured in meter and time can be measured in seconds.
The given problem can be solved as follows,
(1) The cost of sticker in cents is 25.
Since 1 dollar = 100 cents
⇒ 1 cent = 1/100 dollars
⇒ 25 cent = 25/100 = 0.25 dollars.
Thus, the cost of sticker is $0.25.
(2) The cost of the pen is 1.50 dollars.
Since 1 dollar = 100 cents
⇒ 1.50 dollar = 1.50 × 100 = 150 cents
(3) There are 100 cents in one dollar.
(4) There are 1/100 = 0.01 dollars in one cent.
Hence, the answers to all the problems are obtained as $0.25, 150 cents, 100 cents and $0.01.

Step-by-step explanation:
A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?
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.

The dot plot shows the number of classes per semester that a group of boys and girls have chosen to take in their freshman year of college. Which statements correctly describe the two data sets?
The difference of the means is 1.5.
The difference of the means is 0.5.
The difference of the means is about one-third the mean absolute deviation of either data set.
The difference of the means is 1.
The difference of the means is about one-half the mean absolute deviation of either data set.
The correct statement is the difference of the means is 0.5.
What is Box- plot?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

What's the answer to this?
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.
----------------
Extra info:
If a > 1 then the graph is stretched vertically to make it taller than it used to be. Eg: a = 5 leads to the graph being 5 times taller than before which also would make it steeper too. The value of d handles the vertical shifting. If d > 0, then we shift up d units. If d < 0, then we shift down |d| units.Does Each Equation Demonstrate The Distributive Property? Explain.

2) (s - 4) 8 = 8 ( s - 4)

4) 8 + ( t + 6) = ( 8 + t ) + 6
[tex](42 \times 51) + 14 = [/tex]
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.
