Answer:
$96 is the original price of book
Step-by-step explanation:
keep the unknown value as X
(19.2/X)*100 = 20%
19.2/X = 0.2
19.2/0.2 = X
X = 96
The original price of the book is $24.
When there is a sales, the price of items become cheaper. Items become less expensive when there is a sale.
When there is a 20% reduction in the price of the book, the book becomes 80% (100 - 20%) cheaper. In order to determine the original price of the book, divide the sales price by 80%
Original price = $19.20 / 80%
= $19.20 / 0.8
= $24

Write the sentence as an inequality. A number x is no less than –8.
x ≥ -8
Answer choice D is correct
x ≥ -8 represents the given inequality. Option C is correct.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here.
A number x in no less than -8,
Implies that the number x must be equal to -8 or more,
Applying the greater equal to sign(≥) between the x and -8
x ≥ -8
Thus, x ≥ -8 represents the given inequality. Option C is correct.

3:5. Then, it sold four times as many fiction books and 40%
more cartoon books. As a result, it sold 800 more fiction books
than cartoon books. How many fiction and cartoon books were
sold altogether in the end?
Complete question:
A book shop sold fiction books and cartoon books at a ratio of 3:5. Then, it sold four times as many fiction books and 40% more cartoon books. As a result, it sold 800 more fiction books than cartoon books. How many fiction and cartoon books were sold altogether in the end?
Answer:
3040
Step-by-step explanation:
Given the following :
Sales ratio = 3:5 (fiction : cartoon)
Let total number of books sold = x
Fiction books = 3x
Cartoon books = 5x
Four times as many fiction books = 4 × fiction books = 4*(3x) = 12x - - - (1)
40% more cartoon books = 40/100 = 0.4
5x(1.40) = 7x - - - (2)
As a result, 800 more fiction books than cartoon :
Fiction - cartoon = 800
12x - 7x = 800
5x = 800
x = 160
Substitute x into (1) and (2)
Fiction books : 12(160) = 1920
Cartoon books : 7(160) = 1120
1920 + 1120 = 3,040

PLEASE HELP
Answer:
1/2+1/5=7/10
Step-by-step explanation:
1/2=5/10
1/5=2/10
2/10+5/10=7/10
Answer:
0.7 or 7/10
Step-by-step explanation:
When adding fractions they always need to have the same denominators,and the one they both have similar to is being equal to 10.
1/2 will get multiply with 5 on the numinator and the denominator having you get a fraction of 5/10.
You will do the same with 1/5 multiply it with 2 on the numinator and denominator having you get 5/10.
Since the dneominators are the same you keep it 10,and just add 5 and 2. Giving you a answer of 7/10

Find a · b.
a = −5, 1 / 2 ,
b = −5, 6
Answer:
a · b = 28 units
Step-by-step explanation:
Given vectors
a = (-5, 1/2)
b = (-5, 6)
The scalar or dot product of the two vectors, given by a · b is
a · b = (-5, 1/2) · (-5, 6)
To solve this, multiply the first term in a with the first term in b and add the result to the product of the second term in a and the second term in b. i.e
a · b = (-5 x -5) + (1/2 x 6)
a · b = 25 + 3
a · b = 28
Therefore, the dot product of a and b is
a · b = 28 units

Answer:
2/3 is the answer
Answer:
2/3
Step-by-step explanation:
First you add all the colors. Then you subtract that number from 4200 to get the total number of blue buterfiles. After that, you put the total number of blue butterflies in the numerator and the 4200 would go in the denominator. Then you reduce until u get the final fraction.

A regular polygon of n sides has its sum of interior
angles as 900° What is n?
A. 5
B.6
C.7
D. 8
Answer:
C. 7Step-by-step explanation:
n is the number of sides of the polygon
[tex](n - 2) \times 180 = 900[/tex]
Divide both sides of the equation by 180
[tex] \frac{(n - 2) \times 180}{180} = \frac{900}{180} \\ n - 2 = 5 \\ n = 5 + 2 \\ n = 7[/tex]

ej bisects def, m dej-5x+7, m JEF=8x-8. find x
Answer:
x = 5
Step-by-step explanation:
The information given has been sketched out in the attachment below.
Line segment EJ is an angle bisector of angle DEF. Therefore, m<DEJ = m<JEF.
The equation to find x would be expressed as follows:
5x + 7 = 8x - 8
Subtract 5x from each side (subtraction property of equality)
5x + 7 - 5x = 8x - 8 - 5x
5x - 5x + 7 = 8x - 5x - 8
0 + 7 = 3x - 8
7 = 3x - 8
Add 8 to both sides of the equation (addition property of equality)
7 + 8 = 3x - 8 + 8
15 = 3x
Divide both sides by 3
15/3 = 3x/3
5 = x
x = 5
