-- "Perimeter" means all the way around, all four sides.
-- That's two lengths and two widths.
-- So one length and one width is half of the perimeter.
-- If the perimeter is 16-ft, then one length + one width is 8-ft.
-- If the width is 5-ft, then the length is (8 - 5) = 3-ft.
Answer:
(-2,-5)
Step-by-step explanation:
you simply move five units to the left, since you are not going up and down, they Y axis stays the same. The X axis is the one you count.
Answer: Rita's paddling speed in still water is 2.5 miles pet hour and the speed of the river's current is 0.5 miles per hour.
Step-by-step explanation:
Let x represent Rita's paddling speed in still water.
Let y represent the speed of the river's current.
On a canoe trip, Rita paddled upstream (against the current) at an average speed of 2 miles per hour relative to the riverbank. This means that
x - y = 2 - - - - - - - - - - - - -1
On the return trip downstream (with the current) . Her average speed was 3 miles per hour. This means that
x + y = 3 - - - - - - - - - - - - -2
Adding equation 1 and equation 2, it becomes
2x = 5
x = 5/2 = 2.5 miles per hour.
Substituting x = 2.5 into equation 1, it becomes
2.5 - y = 2
y = 2.5 - 2 = 0.5 miles per hour
the answer is -1/2
