3. It took Ellie 4 hours to paddle her canoe 10 km upstream. After a
leisurely 3 hour picnic, she paddled home in 1 hour.
A) How fast did Ellie paddle upstream?
B.) What was Ellie's average speed while paddling?

A) 2.5 km/ hour

You divide 10/4 and get 2.5, so 2.5km an hour.

B) 6.25 km/ hour

You have 2.5km/ hour plus 10km/ hour OVER 2. This would equal 12.5 km over 2

You then get 6.25 from doing 12.5/2

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong
