Convention in algebra is that we use letters such as a, b, c, etc., for parameters and letters such as x, y z, and so on, for variables.
Thus the parameters here are a, b and k. k is the constant of proportionality.
Answer:
Problem 1:
x=12, x=3, x=6
Problem 2:
18*3=54
54/18=3
Problem 3:
Part A: 36/4.5=? 4.5*x=36
Part B: 8
Step-by-step explanation:
-2x + 6 - 13x + 16
= -15x + 22
The answer is 1/3 is the answer.
