In the box there are 34 black marbles, 17 red marbles, 53 blue marbles, and 13 white ones. What fraction of all marbles are not black? I really need help.

the answer is 13/48

step-by-step explanation:

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

differentiate (x^14(x^-2)^4with respect to the variable

the parentheses don't balance in your input.

differentiate 0 with respect to

the final answer is

0

hope this

the correct answer would be the third option
