4 I think it’s 4 because 2x would be 4 and 8
6 kilograms, you divide the mass by 1000
Answer:
n = 2*
Step-by-step explanation:
(4.8 * )n = 9.6 *
Divide both sides by (4.8 * )
(4.8 * ) / (4.8 * ) n = 9.6 * / 4.8 *
n = 9.6 * / 4.8 *
n = 9.6/4.8 * /
n = 2 *
n = 2*
Ok so R=alfonso's rate
w=wind rate=4
d=rt
with wind rate is R+4
agaoins wind rate is R-4
with wind distance is 34
against is 18 miles
time is same
34=(r+4)t
18=(r-4)t
34=(r+4)t
divide both sides by (r+4)
34/(r+4)=t
18=(r-4)t
divide both sides by (r-4)
18/(r-4)=t
18/(r-4)=t
34/(r+4)=t
set equal to each other
18/(r-4)=34/(r+4)
multiply both sides by (r-4)(r+4)
18(r+4)=34(r-4)
distribute
18r+72=34r-136
subtract 18r from both sides
72=16r-136
add 136 to both sides
208=16r
divide both sides by 16
13mph
answer is 13mph with no wind
