torisob [31]

Answer: total books = 180

Step-by-step explanation:

Given: Poetry section of the library has 6 bookcases.

Number of shelves in each bookcase = 3

Total shelves =  (Number of shelves in each bookcase) x (Number of bookcases in each poetry section)

= 3 x 6

= 18

Number of books in each shelf = 10

Total books = (number of shelves) x 10

= 18 x 10

= 180

hence, total books in the poetry section= 180

3(x + 2) = 2x + 14<br> How many solutions
Katarina [22]

Answer:

I solution; x=8

Step-by-step explanation:

You have to solve for x by simplifying both sides of the equation and then isolating the variable

3(x+2)= 2x+14

Distributive Property

3x+6=2x+14

Isolate the variable

3x+6-6=2x+14-6        which is 3x=2x+8

3x-2x=2x-2x+8

x=8

Sergio [31]
The equation would be 400+20c per week so if you do that equation, to figure it out 680-400=280 and then you would divide it by 20 and whatever that answer is, in this case it would be 14.
