She made 15 cookies
<em><u>Solution:</u></em>
Let "x" be the number of cookies she made
She gave 1/3 of cookies for her husband
Therefore,

Find the remaining

1/4 of the cookies to her son
Therefore,

Now again find the remaining

1/6 of a cookies to her neighbor

Therefore,

Thus she made approximately 15 cookies
Answer:
-6/4
Step-by-step explanation:
equivalent, that means something that is equal to so if you break -6/4 to the lowest you get -6/4
Let r(cos O + i sin O) be a cube root of 125(cos 288 + i sin 288)
then
r^3(cos O + i sin O)^3 = 125(cos 288 + i sin 28)
so r^3 = 125 and cos 3O + i sin 3O = cos 288 + i sin 288
so r = 5 and 3O = 288 + 360p and O = 96 + 120p
so one cube root is 5 (cos 96 + i sin 96)
