6+f(28+b(4)=6+112f+4bf
b=6+112f/-4f
b=1*6^0+1*112f^0/1*-4f^0
b=1+1/1
b=2
24/1 divided by 3/8 would be 64. That can be found by finding the reciprocal (inverse) of the second fraction, multiplying the numerators and denominators to get 192/3. Then to simplify, you can divide both numerator and denominator by 3 to get 64/1 or 64. Hope that helps!
The answer is B because I did the math
x = total amount of students in 8th Grade.
we know only one-thrid of the class went, so (1/3)x or x/3 went.
we also know 5 coaches went too, and that the total amount of that is 41.

now, to verify, well, what do you get for (108/3) + 5?
Wouldn't you just do 10 divided by 12
