Determine which numbers the equations can be multiplied by to create opposite terms of the x-variable. 1/2x − 1/4y = −3
− 1/3x + 2/3y = 5

Which number can the first equation be multiplied by?

Which number can the second equation be multiplied by?

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

Cody started biking to the park traveling 15 mph, after some time the bike got a flat so cody walked the rest of the way, traveling 4 mph. if the total trip to the park took 6 hours and it was 46 miles away, how long did cody travel at each speed? solve using rate times time= distance
