Mr. hann is trying to decide how many new copies of a book to order for his students. each book weighs 6 ounces
which ordered pair is a viable solution if x represents the number of books he orders and y represents the total weight of the books, in ounces?
a. (–3, –18)
b. (–0.5, –3)
c. (0, 0)
d. (0.5, 3)

The correct option is C.

Step-by-step explanation:

We have given that:

Weight of each book = 6 ounces

Number of books = x

Total weight of the books = y

x and y must be positive values. x denotes the number of books therefore it could not be a negative value or a fraction or decimal value.

By keeping this point in mind option A,B and D becomes invalid.

Thus the ordered pair with a viable solution is (0,0)

Only 0,0    You don't order negative numbers of books which eliminates the first two pairs.  And you don't order 1/2 a book which eliminates the last pair.

Step-by-step explanation:

If you order 0 shirts they will weight 0 ounces is the only viable solution.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
