480=60(v+s)
480=60v+60s
8=v+s
s=8-v...
480=80(v-s) using s from above we get:
480=80(v-(8-v))
6=v-8+v
6=2v-8
2v=14
v=7, and since s=8-v, s=1
So the rate of the team is 7m/s while the rate of the stream is 1m/s
Answer:
60
The angle acute so my guess is 60
Hope this helps :)
Answer:
(X=Y)=(3,6)
Step-by-step explanation:
5x-4(4x-6)=-9
x=3
y=4x3-6
y=6
The commutative property of multiplication is ab=ba
so
9(x+5)=(x+5)9
(note, some people on this site like to write x2 for x² but that's not how you math correctly., (x+5)9 doesn't mean (x+5)⁹, it means (x+5) times 9)
