Answer:
65 miles every 1 hour
Step-by-step explanation:
Unit rate is found once one of the units is 1. In this case we need to reduce the ratio so that it is 1 hour and we get a unit rate. We can do this by dividing both sided by 2 so that the hours are reduced to 1.
130=2
130/2=65 2/2=1
65=1
65 miles every hour
Very easy
just add up all the meadals
japan is 38
so total=104+88+82+x+44+38=356+x
total of all medals is 421 so to find brittan or x you just subtrac the total from the big total so
356+x=421
subtract 356 from both sides
x=65
brittan won 65 medals
3w + 8 - w = 4w - 2(w - 4)
is an identity
3w-w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
2w - 2w = 8 - 8
0 = 0
zero equal to zero implies that any value of w satisfies the statement 3w + 8 - w = 4w - 2(w - 4) hence it is an identity.
Answer: this depends are you finding it for a shape or in general if it is in general you simply multiply and get 32,886
