I solved this problem by setting 240/80 equal to x/100 . Once you set them equal to each other, multiply 240 and 100 and divide the product by 80 and you get 300.
B=75, not 27
Sorry, I had to use a napkin because I was too lazy to get a paper....let me know if u need me to explain anything
<span>Rewrite the subtraction as addition 3- (-10)
= 3 + 10</span>
X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
