In a classroom of 33 students, the ratio of boys to girls is 3: 8. how many boys are in the class?

There are 9 boys in the class.

Step-by-step explanation:

Given : The total students in the class =33

The ratio of boys to girls is 3:8.

Let the number of boys be 3x and the number of girls be 8x, thus the total number of students =3x+8x=11x

According to the question, we have

Therefore, the number of boys =

Hence, there are 9 boys in the class.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
