how many solutions are there to the equation below?
a. infinitely
b. 1
c. 0

Equation Classification : A. Possible and Determined;  

B. Possible and undetermined and C.    Impossible:

Step-by-step explanation:

A. Possible and Determined: These are equations that admit at least one solution.

Example: 2x = 3 → x = 3

                                     2

B.   Possible and undetermined:

They are equations that have infinite solutions.

Example: x + 2 = x + 2 → The unknown x assumes infinite numerical values. Thus, the equation has infinite solutions.

C. Impossible: Has no solution.

Examples:

0x = 4 → Unable to divide 4 by 0.

y = y + 2 → y - y = + 2 → 0 = +2 → There is no equation without unknown.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator
