Which shows the best use of the associative and commutative properties to make simplifying 2/5 - 15+8 - 1/5 + 3 easier?
O A. [3+ 8 + (-15)) + ((- 6) + 8]
O B. 1}+8+ (-15)] + [3+(-3)
O c. 18+ (- 6)) + (8 + 3+ (-15)
OD. 1} + (-15)) + (8 + (-1) + 3]

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
