172 boys in class
we have total number of students in class = 410
we assume that the number of boys in class = X
Number of girls in class is 66 more then boyes we assume total number of girls = X+66
if we add number of girls and boyes then we found total strength of classX+X+66=4102X+66=4102x=344X=172
number of boys=172number of girls =238

Answer:
y=x-4
Step-by-step explanation:
Because if the common ratio less than 1, then each term is smaller than the previous term. eventually, it will be so small that it basically equals 0 and the next terms are nigligible
it's like this. say you are on one side of a playground
you walk half the distance across,
you then walk half of the disatnce you just walked
you then walk half of the disatnce you just walked
etc
you will never reach the other side because each distance you take is smaller thatn the previous, eventaull the distance will be so small you won't be moving much
So basically u keep the x on one side and the rest on the other. Get a common denominator. to get rid of the half u times both sides by 2.
hope this helps
