1 km = 1000 m and 1m = 100cm
1 km is the same as 1000 m = 1000 x 100 = 100000 cm
There are 862 kilometres so there is 862 x 100000 = 86200000 cm in 862 km.
There would be 27 students in total. You can find this by knowing that since 9 students got an a, and they make up 1/3 of the class, you should do 9(3) and that will give you 27. I hope I was able to help you understand better!
Answer:
y=40/3
Step-by-step explanation:
Cross multiply -> 5(3y-8)=12y
Distributive property -> 15y-40=12y
Subtract 15y on both sides -> -40=-3y
Divide both sides by -3 -> 40/3=y
So, y=40/3
