Question

Dr. Woods has some liquid phosphorus that is at its melting point

temperature. After he takes it out of an oven, he says the temperature of
the phosphorus rose by double its melting temperature. Let x be the
temperature of its melting point and y be its final temperature. Write an
equation to model this situation. The final temperature of the phosphorus
was 132°C. What is its melting point?

Answer 1

Explanation:

We know that the temperature of the phosphorus rose by double its melting temperature. Mathematically, we can express this as:y = x + 2xSimplifying this equation, we get:y = 3xNow, we are given that the final temperature of the phosphorus, y, was 132°C. Substituting this value into our equation, we get:132 = 3xSolving for x, we get:x = 44Therefore, the melting point of the phosphorus is 44°C.
