By doing 3x4 then you get the answer
Answer:
B) 14
Step-by-step explanation:
1/5 + 1/3 = x (don't worry, it's not algebra, I'm just using x as an example)
The common denominator is 15, so you multiply 5 by 3 = 15 and 1 by 3 = 3,
3/15 = 1/5
Then, multiply 3 by 5 = 15 and then 1 by 5 = 5, so it's
5/15 = 1/3
5/15 + 3/15 = 8/15 and then multiply 15 by 2 = 30 (number of students) and because you multiplied 15 by 2, you also multiply 8 by 2 = 16
So it is now 16/30, so you do 30-16 which is 14.
14 students chose Station M (doesn't sound like a good station).
Whoo! Let's go! (I'll stop being cringy now).
So car A travels Distance = 60 km/hr*(1+x)
Car B travels Distance = 75 km/hr(x)
Where x is the time in hours.
Those two equations are equal when on overtakes the other
so:
60 +60x = 75x
60=15x
x=4, but my expression is written to count from when car B commenced travel. So total time is 5 hours from the car A setting off.
Answer: multiply it by the bisector of the photosynthesis.
obviously
Step-by-step explanation:
It is simple, you are converting 150 of 200 into a fraction and reducing it
150/200=15/20
5 goes into 20 4 times
15/20=1/4
1/4=0.75=75%
