We are given with an 18 student class that is working a project worked by pairs. Each pair works on a project. In this case, there are 9 teams of 2 individuals working on a single project. Hence for a year or school year, there are 9 projects accomplished each time.
Number 3 is 100 number 4 is 112
Answer: I'm not entirely sure, but maybe 1/x^2?
Simply cross multiply:
18*m = 6*15
18m = 90
m = 5
Answer:
m, the amount of money in Michael's bank account
t, the total between the two bank accounts
the equation could be 65+m= t
hope this helps :)
