Have a nice day! :)
1/2 hour = 30 mins
30 x 2 = 60 mins = 1 hour
4.5 x 2 = 9
9mph
A and D because x is 1/3y not 3y and x times y would be 48 and yes I'm sure
The slope (“m” in the equation y = mx + b) in this equation is -2 but the slope of the line in which the coins follow is a positive slope meaning that that linear equation cannot capture the coins.
