Answer:
20 minutes
Step-by-step explanation:
Method 1:
(0.75)/(0.25)=(1)/(x)
0.75*1.333333=1, so multiply 0.25 by 1.333333 to find the value of x!
0.25*1.333333=0.33333, or one-third of an hour, or 20 minutes.
Method 2:
(0.75)/(0.25)=(1)/(x)
Cross-multiply
0.75x=0.25
(0.25)/(0.75)=x
x=0.33333 hours
we are given
we have to solve it by completing square method
step-1: Move 5 on right side
step-2: Break middle term
step-3: Add 6^2 both sides
step-3: Solve for x
we wil get two values
First value is
add both sides 6
Second value is
add both sides 6
so, solutions are
