Answer:
The selling price is $17.40
Step-by-step explanation:
x = selling price
x = 12 + 0.45(12)
x = 12 + 5.4
x = 17.4
The final selling price is $17.40.
Percentages are percents of a whole. This means that 45% = 0.45. You can use this to your advangage when solving these types of equations.
Answer:

A ride sharing company offers two options: riding in small cars that can carry up to 3 passengers each, or riding in large vans that can carry up to 6 passengers each. A group of 27 people is going to use the ride sharing service to take a trip. The trip in a small car costs $10 and the trip in a large van costs $15. The group ends up spending $80 total. An equation that represents one of the constraints is 3x+6y=a. What is the value of a?
Answer:
a = 27
Step-by-step explanation:
3x + 6y = a
From the given information, 3 and 6 are the numbers of passengers that cars and vans can take. That means x and y must be the numbers of cars and vans, and a is the total number of passengers.
a = 27

On a shopping trip, Gina buys two books priced $4.99 and $12.99. She also buys 2 notebooks, 2 packs of pencils, and 3 composition books. The books are on sale for 10% off the list price and school supplies are 15% off. The store charges 6.5% sales tax.
Item Cost ($)
Notebooks 2.88
Composition Books 0.79
Pencil Packs 1.89
How much total will Gina spend on her shopping trip? Round to the nearest cent.
Answer:
$28.00
Step-by-step explanation:
$4.99 + $12.99 = $17.98 with 10% of discount =$16.18
$2.88 (2) + $0.79 (3) + 1.89 (2) = $11.91 with 15% of discount = $10.12
$16.18 + $10.12 = $26.30 with 6.5% sales tax = $28.00
Which equations are true for x = –2 and x = 2? Select two options x2 – 4 = 0 x2 = –4 3x2 + 12 = 0 4x2 = 16 2(x – 2)2 = 0
The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2 so option 1st and 4th are correct.
What are the roots of an equation?Roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots.
For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.
The number of roots of an equation depends on the degree of the equation for example number of roots of quadratic equation are 2.
Given the roots
01)
x = -2
square both sides
x² = 4
x² - 4 = 0
02)
x = 2
Square both sides
x² = 4
Multiply by 4 on each side
4x² = 16
Hence "The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2".

Karen's music library contains 18 fewer playlists than Clarann's music library. The total number of playlists on both music libraries is 40. Find the number of playlists on each person's music library.
Answer:
let Karen's music library be represented by K
let Clarann's music library be represented by C
C = K +18
C +K =40
put C = K +18 into (C +K =40)
K + 18 +K =40
2K +18 = 40
collect like terms
2K =40 -18
2K =22
divide both sides by 2
K =11
since C = K+18
C= 11 +18
C =29
Karen's music library contains 11 playlists while Clarann's music library contains 29 playlists

What is the value of x in the equation 3x/4=24
Answer:
X= 32
Step-by-step explanation:
Answer:
X = 32
Step-by-step explanation:
If you do 24 x 4 you will get 96.
From there you have to divide 3 by 96, since 3 times x has to equal to 96. Since 24 x 4 is 96 and you need to divide 3x by 4.
After you do 96/3 you will get 32. Thus the answer being 32.
Hope this helps!
