Adam sells medical magazines
velikii [3]

Let the Price of 1 magzine = x

       Margin on 1 Magzine = (10%)(x) rupees = 0.1 x    

       Margin on 42 Magzines = 42(0.1 x) = 4.2 x    

Also

Let the Price of 1 books = y

       Margin on 1 Book = (15%)(y) rupees = 0.15 y    

       Margin on 14 Books = 14(0.15 x) = 2.1 y    

Basic Pay of Adam = 200

Amount that Adam earned last week = 200 + 4.2 x  + 2.1 y

What is the location of (-3,-4) after it has been reflected over the x axis? 1) New ordered pair 2) Explain what changes in the
geniusboy [140]

Answer:

The new ordered pair would be (-3, 4)

Step-by-step explanation:

The change would just be a change of the symbol of the y value. This is because a reflection over the x-axis will not change the x value and will give you a y on the other side.

Solve: 5 (x+2) +2x<br> make sure to show your work
Kazeer [188]

Answer:

5 (x+2) +2x is equal to 7x + 10

Step-by-step explanation:

To find the value of this equation you would have to apply the distributive property by changing 5 (x+2) to 5x +10. (When applying the distributive property you will always multiply the numbers in the parentheses by the number on the left of it). Then you would combine like terms by adding 2x and 5x together. You will then have 7x + 10.

Please see picture to solve the volume of this figure.
Gemiola [76]

For this case we have that by definition, the volume of a rectangular prism is given by:

V = a * b * c

Where:

a: Long

b: Width

c: High

Prism 1:

V_ {1} = 7 * 6 * 1 = 42 \ cm ^ 3

Prism 2:

V_ {2} = 7 * 3 * 4 = 84 \ cm ^ 2

Thus, the total volume is:

V = 42 + 84 = 126 \ cm ^ 3

Answer:

126 \ cm ^ 3
