Rhianna and Myra, both teachers, are adding books to their class libraries. Rhianna's classroom started out with a collection of

only 11 books, but she plans to purchase an additional 2 books per week. Myra's library started out with 6 books, and she has enough money in her budget to purchase another 3 books per week. At some point, the two teachers' libraries will contain the same number of books. How many books will each class have? How many weeks will that take?

A dealer bought 3 gross buttons at $.38 a dozen. He sold the buttons at 5 cents each. How much was his profit per gross?(12 doze
777dan777 [17]

Answer:

$2.64

Step-by-step explanation:

Selling them at 5 cents each ($0.05), he could sell 1 dozen buttons for

12 * $0.05 = $0.60

As he bought them at $0.38 per dozen, the profit per dozen would be

$0.60 - $0.38 = $0.22

As 12 dozen is 1 gross, the profit per gross would be

12 * $0.22 = $2.64

The ordered pair (1, -2) is a solution to the system of linear equations.
vesna_86 [32]

Answer:

False

Step-by-step explanation:

2x + y = 0

Try (1, -2)

2(1) + (-2) = 0

2 + (-2) = 0

0 = 0

The solution works on the first equation.

-x + 2y = 5

-(1) + 2(-2) = 5

-1 - 4 = 5

-5 = 5

The solution does not work in the second equation.

Answer: False

I nee d help with this because my teacher didn't explain it well.
koban [17]

To solve 10x-35+3ax=5ax-7a, we'll need to assume that a is a constant and that we are to solve for the variable x.  To accomplish this, group all the x terms together on one side and all of the no-x terms on the other:

10x + 3ax - 5ax = -7a + 35

Factoring x out of the left side, we get:

x(10 - 2a) = 7(5 - a).  Dividing both sides by (10 - 2a), we get:

       7(5 - a)

x = ------------ = 7/2

      2(5 - a)

x has the value 7/2.
