Final answer:
To solve the equation 20/30 = 18/v for v, use cross-multiplication to get 20v = 30 × 18, then divide both sides by 20 to isolate v, resulting in v = 27.
Step-by-step explanation:
Solution for Solving the Proportion
1. Identify the known: y = 30.00.
2. Identify the unknown: We are aiming to find v in terms of another variable. Here, it's represented by c, but in the given equation, no c is present. We'll proceed with solving for v as the unknown.
3. To find v, we can use the concept of cross-multiplication derived from the property of proportions. Given the proportion 20/30 = 18/v, we multiply 20 by v and 30 by 18. So the equation becomes 20v = 30 × 18.
4. To isolate the variable v, divide both sides of the equation by 20, resulting in v = (30 × 18) / 20.
5. Simplify to get the solution for v, which is v = 27.
