Answer:
1648
Step-by-step explanation:
5/9 are girls. The 9 represents the total.
Set up a proportion and you have
5/9 = ?/3708
3708/9=412
412x5= 2060 girls
3708-2060= 1648

So the answer is C. There is no solution, because the equation is false
A and B choices both have the answer, the value of x.
D choice only when the equation is true like 2=2.
