the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

to find the total number of combinations, multiply the quantity of each item by each other:

$26,725 i look it up bro np

16 b

17 d

step-by-step explanation:

16.

amount = 3250(1.06) ^3.5 = 3985.23

17.

m = 9pn

divide both sides by 9n: -

p = m/9n
