Help fast Alvin is running at a rate of 3 meters per second. The meters he runs, m, in s seconds is given by the equation m=3s. Identify the dependent and the independent variable. Explain your reasoning.

m=  dependent variable , s =independent variable because the distance he runs depends on the time.

Step-by-step explanation:

In an experiment, the experimenter manipulates the independent variable to see the change in the dependent variable.

Here, Distance is the dependent variable that depends on time i.e. time = independent variable.

The meters he runs, m, in s seconds is given by the equation m=3s.

Thus, m=  dependent variable , s =independent variable because the distance( meters) he runs depends on the time( seconds).

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
