Answer:
2
Step-by-step explanation:
Complementary is 90 when added up and the other one is 180
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
Answer:
B
Step-by-step explanation:
rise over run the y-intercept is 3 and you go down 4 and run 3
I would say to start with this equation: 20-4+3-5=14 then I would say that the absolute value is 14 or -14 I am sorry if I am wrong!
