It is 5
2x2 -4x +6-1= 0 is the standard form
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:
5x
Step-by-step explanation:
4(2x+3)-3(x+4)
4(2x) + 4(3) - 3(x) - 3(4)
8x + 12 - 3x - 12
8x - 3x + 12 - 12
5x
Answer:
2( 4x + 3y)
Step-by-step explanation:
5x +3x + 2y + 4y
<em>Combine</em><em> </em><em>like</em><em> </em><em>terms</em><em>.</em>
8x + 6y
<em>Factorize the answer.</em>
<u>2( 4x + 3y)</u>
Answer:
multiply the percent
20%=0.2
130x0.2=26
26 copies were already made
130-26=104
104 more copies need to be made
