A) 42,000m divided by 2 1/3 = 18,000m divide by 1000m to get km = 18km/hr
B) 18,000m divided by 60 to get minutes = 300m divide by 60 to get seconds = 5m/sec.
Answer:
The value of x taking denominator common is
Step-by-step explanation:
Given expression as :
=
or, - = 0
Or, - = 0 (multiply numerator and denominator by 5 )
Now taking denominator as common
Or, ( 3 - 5 x ) = 0
Or, = 0 and (3 - 5x ) = 0
∵ (3 - 5x ) = 0
So, 5 x = 3
∴ x =
Hence The value of x taking denominator common is Answer
5 ) 8 × x = 72
6) length = 9m
Step-by-step explanation:
5.
8 × x = 72 ( area of rectangle = l×b)
6. solving the equation
8 × x = 72
x = 72 / 8
x = 9 m
length = 9m
For this case we must simplify the following expression:
We apply distributive property on the left side of the equation:
We subtract 3n from both sides of the equation:
We subtract 6 from both sides of the equation:
We divide between 45 on both sides of the equation:
