Determine the number of girls in a math class with 91 students, if there are 180 girls for every 184 boys?

explain how you got answer

45

Step-by-step explanation:

180 + 184 = 364

If there are 180 girls for every 184 boys, then there are 180 girls for every 364 students.

The fraction of girls is 180/364 = 45/91

If a class has 91 students, and the fraction of girls is 45/91, then there are

45/91 * 91 = 45 girls

first set the equation equal to zero and solve for x using the quadratic formula because it can’t be factored. the solutions will be your x intercepts. to find to vertex, use x=-b/2a. then plug that x value in the original equation and figure out the y coordinate.
