Question

Marie heated water in a beaker. When she began, the water had a temperature of 40 degrees, and she heated it at a rate of 2.5 degrees per minute. Kathy heated water in a different beaker. When she began, the water had a temperature of 50 degrees, and she heated it at a rate of 1.5 degrees per minute. Which equation could be used to determine how many minutes passed before the water temperature in both beakers was the same?

Answer 1

Answer:

2.5x + 40 = 1.5x + 50

Step-by-step explanation:

To find how many minutes passed before the water temperature in both beakers are the same, you need to set both of the expressions that show how hot the water in each beaker is to be equal to each other
