Answer:
C. X=6 or X= -9
First Explanation:
2x + 3 - 3 = 15 - 3 (subtract 3 from 3 and 15)
You should get 2x = 12
Then divide 2x by 2
Divide 12 by 2 which you should get
X = 6
Second Explanation:
2x + 3 - 3 = 15 - 3 (subtract 3 from 3 and 15)
You should get 2x = -18
Then divide 2x by 2
Divide -18 by 2 and you should get
X = -9
Answer:
Since,
Length is 4 times Breadth
Let Breadth be x
Therefore,Length=4x
Perimeter=50m
Therefore,
50m=2(l+b)
50m=2(4x+x)
50m=2(5x)
50m=10x
x=5m.
Therefore,
Breadth=5m
Length=4x=4×5=20m
It's 60 minutes because 450÷10 is 45 so he has to bike for 45 minutes and a 15 minute break would make it 60 minutes
Answer:
3/20
Step-by-step explanation:
3/5*1/4=3/20
Answer:
20mph
Step-by-step explanation:
