According to the information given, there are 21 girls in the ninth grade.

If the number of boys in ninth grade is 12 less than twice the number of girls there are 51 astudents in ninth grade then the number of girls is 21

More than likely not but it depends on how many credits you had before you entered the 10th grade and how many subjects you had during the 10th grade. More important than how many subjects you failed is how many you passed.

The answer depends on credits for WHAT!

Let's say the number of girls is x and the number of boys is y. Then the information we have is: There are 51 students, so: x + y = 51 And 12 less than twice the number of girls are boys, so: y = 2x-12 Replace y in the first equation with the second and you get: x + (2x-12) = 51 3x = 63 x = 21 So there are 21 girls in the ninth grade. To check back, that means there should be 30 boys, and that is indeed 12 less than twice the number of girls.
