Answer:

1. To solve the equation A=c+rvf for v, we need to isolate v on one side of the equation. Here's how we can do it step-by-step:

- Start with the equation A=c+rvf.

- Subtract c from both sides to isolate the term with v: A-c=rvf.

- Divide both sides of the equation by rf to solve for v: (A-c)/rf = v.

Therefore, the correct answer is B. v=A-c/rf.

2. Let's check each option to see which one is not equivalent to v=1/3bh:

A. B=3v/h: This equation is equivalent to v=1/3bh, as it rearranges the variables without changing the meaning. So, this option is equivalent.

B. V=1/3hb: This equation is equivalent to v=1/3bh, as it rearranges the variables without changing the meaning. So, this option is equivalent.

C. 3=bhv: This equation is not equivalent to v=1/3bh because the order of the variables is different. In v=1/3bh, b and h are multiplied, while in 3=bhv, b, h, and v are all multiplied together. So, this option is not equivalent.

D. H=3v/b: This equation is equivalent to v=1/3bh, as it rearranges the variables without changing the meaning. So, this option is equivalent.

Therefore, the correct answer is C. 3=bhv, which is not equivalent to v=1/3bh.
