Tania knows that the ratio of boys to girls in her class is 3:5. Since 20 of the students are girls, she says that there must be 30 students in her class. Is she right? Explain your thinking.

No, there are 32 students in her class.

Step-by-step explanation:

The ratio to boys and girls is

There are 20 girls in the classroom.

32 students in the classroom

Step-by-step explanation:

Let the no. of students be x, so

3/8x + 20 = x

3/8x - x = -20

-5/8x = -20

Multiply both sides by -8/5,

x = 32

the answer will be

p(x)= 8 x³ - 36 x² + 54 x - 27

q(x) = 2 x -3

you can check your mistake and then you can choose the correct option.

dividend =   8 x³ - 36 x² + 54 x - 27

divisor = 2 x -3

if you want to find quotient, proceed as follows

q(x)= 0

2 x - 3=0

x =

now , i have used division method , to find quotient and remainder
