Question

In a certain county, the number of charter schools is 6 less than twice the number of alternative schools. We know that there are 52 charter schools in the county. How many alternative schools are in the county?

58
44
29
23

Answer 1

c = 2a - 6
c = 52

52 = 2a - 6
52 + 6 = 2a
58 = 2a
58/2 = a
29 = a <=== there r 29 alternative schools
