B.) 5x+9y=6
C.) 5/9x+y=2/3
D.) -5x+9y=6
Answer:
5/9x+y=2/3
Step-by-step explanation:
Since we are looking for distance, we have to convert the 2nd part (which is the speed) to dostance.
Distance = speed x time
Distance = 5 x 2.25 = 11.25
In the first part, he drove for 3.5 hours. And in the 2nd part, he drove for 2.25 hours which sum up together to be 5.75 hours.
Since we have the distances for both parts now, we just sum it up
which it 168 + 11.25 = 179.25 miles
I hope this is good
The simplified form of 18/28 is 9/14.
The given fraction is,
18/28
Since we know that,
Finding the simplest form of any fraction is a straightforward procedure. We must simplify the fraction's numerator and denominator by dividing them both by the greatest common factor that divides them entirely. Both the numerator and denominator should be full integers after division. This method of fraction reduction is also known as fraction reduction.
Therefor,
Divide numerator and denominator by 2 we get,
⇒ 9/14
Hence,
9/14 is the simplest form of 18/28.
