Abdul buys dress pants from a clothing Company for P dollars he sells each pair of pants in his men's clothing shop at 40% markup select all the expressions below represent the new retail price of a pair of dress pants
Answer:
$P + 0.4P or 1.4P
Step-by-step explanation:
Given that:
Cost of dress pants = $P
Markup on cost price = 40%
The new retail price of a pair of dress pant :
(Cost price of the dress pant + markup on cost price)
$P + 40% of P
$P + 0.4P
New retail price = $P + 0.4P = 1.4P

Answer:
-(4 x^2 - 5 x + 28)
-4 x^2 + 5 x - 28
-1\/16 (8 x - 5)^2 - 423\/16
Step-by-step explanation:
any of these equations are equal to 3x^2+5x-7(x^2+4)
The equivalent expression is -4 x² + 5 x - 28.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The fifth term of an AP is 25 and the fifteenth term is 75 .Find the 10th term
Answer: I think it's 50
Step-by-step explanation:
5 = 25
15 = 75
Presumeably, 10 = 50
Answer:
50
Step-by-step explanation:
5th term=a+4d
10th term=a+9d
15th term=a+14d
since
5th term=25 and the 15th term=75
so we find the value of unknown 'd' with is the common difference
a+4d=25
a+14d=75
-10d=-50
d=5
after finding the value of d we can now find the value of 'a'
a+4(5)=25
a=5
hence the 10th term can be obtained
a+9d
5+9(5)=50

3x = 105 (divide by 3 on both sides)
x = 35 or 105/3
6.) a
-5x - 25 = 78 (1st add 25 on both sides)
-5x = 103 (2nd divide both sides by -5)

One ninth of the students in Mr. Beck’s class list red as their favorite color. Twice as many students call blue their favorite, and three times as many students prefer pink. The rest name green as their favorite color. If 6 students call blue their favorite color, how many students are in Mr. Beck’s class?
Answer:
27
Step-by-step explanation:
this is because 6 students is 2/9th of the class and if we divide that by two we get 3. 3 is 1/9th od the class so we multiply it by 9 to get 27 which is how many students should be in his class if i am right

Twice the square of a number is less than another number. Negating the square of that number and adding 5 causes
it to be larger than the other number. Which represents the solution set?
Answer:
d
Step-by-step explanation:
took it on edg
The graph d represents the solution set of the inequalities 2x^2 < y and -x^2 + 5 > y
How to represent the solution set?First, we represent the mathematical statements as an equation or inequalities
Mathematically, the statements in the questions are:
2x^2 < y-x^2 + 5 > yWhere x and y represents the two numbers
So, we plot the graphs of 2x^2 < y and -x^2 + 5 > y
The graph d represents the solution set of the inequalities 2x^2 < y and -x^2 + 5 > y

At a college bookstore, Tanisha bought a Math Textbook and a Novel for $54. If the price of the Math Textbook is $8 more than 3 times the price of the Novel, then how much is the price of each book?
Answer: Price of Math Textbook= $42.5, Price of the Novel= $11.5
Step-by-step explanation:
Let x = price of the Novel.
Price of Math Textbook = 8+3x
As per given , we have
Price of Math Textbook + Price of the Novel = $54
⇒ 8+3x+x = 54
⇒ 8+4x=54
⇒ 4x = 46 [subtract 8 from both sides]
⇒ x = 11.5
Price of Math Textbook = 8+3(11.5) = 8+34.5= $42.5
Hence, Price of Math Textbook= $42.5, Price of the Novel= $11.5

Aron charges an initial service fee of 10$ plus 15$ per hour , what is X?
Answer:
The linear function becomes:
y = 15x + 10
Here, 'x' is the number of hours, b=10 is the initial service fee i.e. $10, 15 is slope or rate of change, and 'y' is the cost.
Step-by-step explanation:
We know that the slope-intercept of a linear function is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Note: Slope is also termed as the 'rate of change'.
Given that Aron charges an initial service fee of 10$.
Thus, the y-intercept = b = 10
As the rate of change = 15$ per hour
so the slope = m = 15
Therefore, the linear function becomes:
[tex]y = mx+b[/tex]
y = 15x + 10
Here, 'x' is the number of hours, b=10 is the initial service fee i.e. $10, 15 is slope or rate of change, and 'y' is the cost.
For example, in one hour i.e. x = 1, the cost 'y' will be:
y = 15x + 10
y = 15(1) + 10
y = 25 + 10
y = $25
Therefore, in one hour (x=1), the cost will be: y = $25
