Three-fifths of the students in a room are girls. one-third of the girls have blond hair. one-half of the boys have brown hair.
a. what fraction of all the students are girls with blond hair?
b. what fraction of all the students are boys without brown hair?

a. Of all the students, are girls with blond hair.

b. Of all the students, are boys without brown hair.

Step-by-step explanation:

a. You know that of the students are girls (This means that of the studes are boys) and of these girls have blond hair.

Then, of is:

Therefore, of all the students, are girls with blond hair.

b. You know that of the boys have brown hair.

Then, of is:

Of all the students, are boys without brown hair.

the correct is answer is a 9-sided polygon!

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
