Find the value of each of the variables. a. x=12,y=15,z=20 b. x=9,y=15,z=20 c. x=9,y=18,z=20 d. x=12, y=18,z=20

The answer is not A. It is B. I got it right on the quiz!

Step-by-step explanation:

x/12=12/16, then do the cross butterfly method.

144=16x || 9=x

25/y=y/9 || 225=y || 15 = y

25/z=z/16 || 400=z || 20=z

x=9, y=15, z=20

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
