<span>(-1/2)(4)(-2)(7y)(-1)

Just start multiplying!

-1/2 * 4 = -2
-2 * -2 = 4
4 * 7y = 28y
28y * -1 = -28y

Since that's not an option I suspect you're missing an x.</span>

Upstream - 2 miles per hour

Downstream - 3 miles per hour

Step-by-step explanation:

For the speed downstream, the answer would be 3 miles per hour (mph), because 6÷2=3.

Both answers come in similar methods. Hope this helps you!

1) How many 3/4 does it take to make 9/2?


     Now look at this, 3/4 x 6 = 4 1/2.  4 1/2 is the same as 9/2


   3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 ---> takes 6, 3/4's to make 9/2

2)  How many 3/4's go into 9/2?


    This is the same question as the 1st one so the answer is 6 :)


3)  9/2 divided by 3/4 = ??


         Use the KEEP< CHANGE< FLIP method, so it turns into  I

                                                                                                    I
      9/2 x 4/3                       < -------------------------------------          I


  This is equal to 36/6 which is 6 :)


The answer is 6 for numbers 1, 2, and 3 :)
