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

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

I need to now the measurements on of A and B
Answer:
A = 90° and B = 145°
Step-by-step explanation:
We already know that A is a right angle because it looks just like one. A trapezoid has a total of 360 degrees. We can create an equation to solve for the 4th angle.
90 + 90 + 145 + x = 360
325 + x = 360
x = 35
Now, we can find B. Angle B and 35 make a supplementary angle. This means that both angles when added will equal 180 degrees. We can create an equation and solve.
35 + B = 180
B = 145
Best of Luck!

a) 85 degrees
b) 65 degrees
c) 75 degrees

Step-by-step explanation:
Since it is a regular pentagon, all five sides are equal and you know one side is x-3. Thus the equation would be: x-3 = 18.8/5
x - 3 = 18.8/5
= 3.76
x = 3.76 + 3
x = 6.76

Determine if the pair of lines are parallel perpendicular or intersecting
Answer:
1. y= 2/3x + 4, and y = 2/3x - 1 are parallel
2. y = 1/3x - 3 and y = 2x + 5 are perpendicular
3. y =2/5x +4 and y = 0.2x - 1 are intersecting
4. y = -x + 13 and y = x-14 are perpendicular
Step-by-step explanation:
The equation of lines are solved and parallel lines are
a) y = 2/3x + 4 , y = ( 2/3 )x - 1
Perpendicular lines , y = -( 1/2 )x - 3 , y = 2x + 5
Intersecting lines
a) y = ( 2/5 )x + 4 , y = 0.2x - 1
b) y = -x + 13 , y = x - 14
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
y = 2/3x + 4 , y = ( 2/3 )x - 1
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = 2/3
So , the slopes of the two lines are same and they are parallel lines
And , y = -( 1/2 )x - 3 , y = 2x + 5
The slopes are negative reciprocals of each other , so they are perpendicular lines
Now , the intersecting lines are a) y = ( 2/5 )x + 4 , y = 0.2x - 1
b) y = -x + 13 , y = x - 14
Hence , the equation of line is solved

I am the one who commented on your question "Who's good at Math", I am the locrival one to be specific but for me, the answer would be the first choice which is the "f(x)=400+15(x-40)". The first choice is my answer because if you compute it the equivalent is 13.3, it is also my answer because for all the choices, it is the only one positive.

The price of a computer component is decreasing at a rate of 10% per year. State whether this decrease is linear or exponential. If the component costs $ 110 today, what will it cost in three years?
Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=[tex]ab^{x}[/tex]
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
[tex]y= 110(0.9)^{x}[/tex]
Now, to find the cost in 3 years, use x as 3.
[tex]y=110(0.9)^{3}[/tex]
Which is simplified to
y=$80.19
