Hey I need help in math (I’m not good at it lol)

After the seventh month of a 12-month loan: the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = , and the denominator is: {(n) + (n + 1) + + (n + 11)} = . therefore, the fraction is numerator/denominator (to the nearest tenth) = %

Which is the equation of a line perpendicular to the line with the equation 3x+4y=8

If your teacher tells you to do questions 6 through 19 in your math book for homework, how many questions is that
