Answer:
Pretty sure its E sorry if I'm wrong I learned this like 2 years aho
If there are 20 red seeds in each bag, then there are 20*2=40 green seeds in each bag.
There are 40*5=200 green seeds in 5 bags.
S=vt
s=8 t=32
8=32v
v=0.25
the answer is
s=0.25t
(the unit of s is mile, the unit of t is min)
Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)
36/63 in its simplest form is 4/7
Have a great day! =)
