Abox in a college bookstore contains books, and each book in the box is a history book, an english book or a science bok. if 1/3 of these books are history books and 1/6 of these books are english books, what fraction of the books are science books?

1/2

Step-by-step explanation:

If 1/3 is history and 1/6 english

1/3 = 2/6

2/6 = history 1/6 = english 3/6= left

that 3/6 left (aka 1/2) is science

21

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
