Answer:
∠ ABC = 40°
Step-by-step explanation:
the 3 angles lie on a straight line ABE and sum to 180° , that is
50 - x + 80 + 2x + 40 = 180
x + 170 = 180 ( subtract 170 from both sides )
x = 10
Then
∠ ABC = 50 - x = 50 - 10 = 40°

30 minutes is half of an hour so it would be 50%.
N is the number
divided by 6 then n/6
5 was taken away so (n/6)-5
the result is multiplied by 2 so 2((n/6)-5)
result is -12
-12=2((n/6)-5)
divide both sides by 2
-6=(n/6)-5
add 5
-1=n/6
times 6
-6=n
da number was -6
Answer:
250
Step-by-step explanation:
If Bulan's team rows their boat at a rate of
2
minutes per
500
meters, they row at a rate of
1
minute per
250
meters. We know this because
1
minute is
1
2
of
2
minutes, and in this time, they will have to have rowed
1
2
the distance they would row in
2
minutes (
500
m).
1
2
of
500
is
250
.
So, we now have the rate in min/m.
If, every
1
minute, Bulan's team rows
250
meters, this means that every
250
meters, they have rowed for
1
minute.
Bulan's team's rowing rate in m/min is
250
m/
1
min.
