Step-by-step explanation:
there you go hope this helps
Answer:
<u><em>1st equation:</em></u>
Simplify the numerator
(zero divided by any number (other than zero) is zero)
1st equation is correct
<u><em>2nd equation:</em></u>
This is because a negative number divided by a positive number is a negative number.
So, 
is incorrect.
2nd equation is incorrect
The least common multiple of each is 2. 2 x 25= 50. 2 x 30= 60 and 2 x 36=72
Remark
Start by figuring this out for 1 car. Worry about the 7 part when you find 1.
This problem is used quite frequently in physics. For example resistors in parallel use the same equation.
Formula
1/frank + 1/carla + 1/missy = 1/ time taken to do 1 mar.
Givens
Frank = 2 hours
Carla = 2 hours
Missy = 3 hours.
Substitute and Solve
1/2 + 1/2 + 1/3 = 1/Three_together.
3/6 + 3/6 + 2/6 = 1/Three_together.
8/6 = 1/Three_together. Cross multiply
8 * Three_Together = 6*1
8 * Three_Together = 6 Divide by 8
Three_Together = 6/8 = 3/4 = 0.75 hours. or 45 minutes for 1 car
Seven Cars
For 7 cars multiply 0.75 by 7
7 * 0.75 = 5.25 hours. <<<< Answer
