The ratio of boys to girls in mr. bakers class is 2 to 3. if there are 30 total students in class , how many more girls are in the class than boys?

I'm confused on this could anyone me and show me what i need to do to solve it.

For [tex]f(x) = 4x + 1[/tex] and (x) = [tex]g(x)= x^{2} -5,[/tex] find [tex](\frac{g}{f}) (x)[/tex]a. [tex]\frac{x^{2} - 5 }{4x +1 },x[/tex] ≠ [tex]-\frac{1}{4}[/tex]b. x[tex]\frac{4 x +1 }{x^{2} - 5}, x[/tex] ≠ ± [tex]\sqrt[]{5}[/tex]c. [tex]\frac{4x +1}{x^{2} -5}[/tex]d.[tex]\frac{x^{2} -5 }{4x + 1}[/tex]

Choose the correct translation for the following statement. it is at most ten. x< 10 x< 10 x> 10 x> 10
