Answer:
rate of the current = 2 mph
Step-by-step explanation:
d = rt
Let c = rate of the current
Rate going downstream = c + 40
Time going downstream = 126/(40 + c)
Rate going up stream = 40 - c
Time going upstream = 114/(40 - c)
Since the times are equal, then
126/(40 + c) = 114/(40 - c)
126(40 - c) = 114(40 + c)
5040 - 126c = 4560 + 114c
240c = 480
c = 2 mph
Answer:
true
Step-by-step explanation:
It would be 1/8 and 1/2 but somehow if not 1/2 then 1/10 I can assure you that I hope this helps
Answer: B
Step-by-step explanation:
the reason the answer is B is because you want to:
1st. count how many down or up on the the Y line. In this case its 2 down which is -2.
2nd. count the boxes over. It's 2 boxes over so that gives u your top number.
3rd and final step. you count up till you reach the top point. that 5 space and so 5 is your bottom number.
Here's a trick that I use. I draw a triangle. Once u plot the points you connect them with a line is the line is going left its a negative of its going right its a positive.
then while you count the blocks draw a line in the end it turns into a triangle.
Here's a example.
PS. the top number of the fraction and the last number always match. Thats another way you can tell if its a negative or a positive.
