Let the length of river D be x
then the lenght of river C will be 200+x
but,
lenght of river C+lenght of river D=5580
x+x+200=5580
2x=5380
x=2690
Therefore lenght of river D is 2690 and that of C is 2890
Hope this helps
Something to remember is how to multiply terms with same bases, but different exponents:

Essentially, we add the exponents.
Using the information above, we can find our answer:

Our answer is
, or A.
$22* (150/100)= $33.
150% of $22 is $33~
Your Slope is 2/3
Find one point then find the other, and do how many times you rose to get to the other point, over how many times you ran.
-16 + 4x = 20
