Two joggers start from opposite ends of an 8 mile course running towards each other. one jogger is running at a rate of 4 mph. the other is running at a rate of 6 mph. after how many minutes will the joggers meet?

Which expression is equivalent to? assume x > 0 and y > 0.

Explain why the factor 1.5 is broke. into two numbers in the model.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
