A gear makes 50 revolutions each minute. It can be represented by the equation r-50t, where r is the total revolutions and t is the number of minutes. Which is the correct answer and explain. Bennett says that it will take more than 7 minutes to make 300 revolutions
or
Betty says that 50 represents the constant of proportionality, k.

I believe Betty

Step-by-step explanation:

Betty because bennet says 300 divided by seven is 50 but is 42

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
